       git config [<file-option>] -e | --edit


DESCRIPTION
       You can query/set/replace/unset options with this command. The name is actually the section and the
       key separated by a dot, and the value will be escaped.

       Multiple lines can be added to an option by using the --add option. If you want to update or unset an
       option which can occur on multiple lines, a POSIX regexp value_regex needs to be given. Only the
       existing values that match the regexp are updated or unset. If you want to handle the lines that do
       not match the regex, just prepend a single exclamation mark in front (see also the section called
       "EXAMPLES").

       The type specifier can be either --int or --bool, to make git config ensure that the variable(s) are
       of the given type and convert the value to the canonical form (simple decimal number for int, a
       "true" or "false" string for bool), or --path, which does some path expansion (see --path below). If
       no type specifier is passed, no checks or transformations are performed on the value.

       When reading, the values are read from the system, global and repository local configuration files by
       default, and options --system, --global, --local and --file <filename> can be used to tell the
       command to read from only that location (see the section called "FILES").

       When writing, the new value is written to the repository local configuration file by default, and
       options --system, --global, --file <filename> can be used to tell the command to write to that
       location (you can say --local but that is the default).

       This command will fail with non-zero status upon error. Some exit codes are:

        1. The config file is invalid (ret=3),

        2. can not write to the config file (ret=4),

        3. no section or name was provided (ret=2),

        4. the section or key is invalid (ret=1),

        5. you try to unset an option which does not exist (ret=5),

        6. you try to unset/set an option for which multiple lines match (ret=5), or

        7. you try to use an invalid regexp (ret=6).

       On success, the command returns the exit code 0.

OPTIONS
       --replace-all
           Default behavior is to replace at most one line. This replaces all lines matching the key (and
           optionally the value_regex).

       --add
           Adds a new line to the option without altering any existing values. This is the same as providing
           ^$ as the value_regex in --replace-all.

       --get
           Get the value for a given key (optionally filtered by a regex matching the value). Returns error
           code 1 if the key was not found and error code 2 if multiple key values were found.

       --get-all
           Like get, but does not fail if the number of values for the key is not exactly one.

       --get-regexp
           Like --get-all, but interprets the name as a regular expression and writes out the key names.
           Regular expression matching is currently case-sensitive and done against a canonicalized version
           of the key in which section and variable names are lowercased, but subsection names are not.

       --global
           For writing options: write to global /.gitconfig file rather than the repository .git/config,
           write to $XDG_CONFIG_HOME/git/config file if this file exists and the/.gitconfig file doesn't.

           For reading options: read only from global ~/.gitconfig and from $XDG_CONFIG_HOME/git/config
           rather than from all available files.

           See also the section called "FILES".

       --system
           For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository
           .git/config.

           For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all
           available files.

           See also the section called "FILES".

       -f config-file, --file config-file
           Use the given config file instead of the one specified by GIT_CONFIG.

       --remove-section
           Remove the given section from the configuration file.

       --rename-section
           Rename the given section to a new name.

       --unset
           Remove the line matching the key from config file.

       --unset-all
           Remove all lines matching the key from config file.

       -l, --list
           List all variables set in config file.

       --bool

           git config will ensure that the output is "true" or "false"

       --int

           git config will ensure that the output is a simple decimal number. An optional value suffix of k,
           m, or g in the config file will cause the value to be multiplied by 1024, 1048576, or 1073741824
           prior to output.

       --bool-or-int

           git config will ensure that the output matches the format of either --bool or --int, as described
           above.

       --path

           git-config will expand leading ~ to the value of $HOME, and ~user to the home directory for the
           specified user. This option has no effect when setting the value (but you can use git config bla
           ~/ from the command line to let your shell do the expansion).

       -z, --null
           For all options that output values and/or keys, always end values with the null character
           (instead of a newline). Use newline instead as a delimiter between key and value. This allows for
           secure parsing of the output without getting confused e.g. by values that contain line breaks.

       --get-colorbool name [stdout-is-tty]
           Find the color setting for name (e.g.  color.diff) and output "true" or "false".  stdout-is-tty
           should be either "true" or "false", and is taken into account when configuration says "auto". If
           stdout-is-tty is missing, then checks the standard output of the command itself, and exits with
           status 0 if color is to be used, or exits with status 1 otherwise. When the color setting for
           name is undefined, the command uses color.ui as fallback.

       --get-color name [default]
           Find the color configured for name (e.g.  color.diff.new) and output it as the ANSI color escape
           sequence to the standard output. The optional default parameter is used instead, if there is no
           color configured for name.

       -e, --edit
           Opens an editor to modify the specified config file; either --system, --global, or repository
           (default).

       --[no-]includes
           Respect include.*  directives in config files when looking up values. Defaults to on.

FILES
       If not set explicitly with --file, there are four files where git config will search for
       configuration options:

       $GIT_DIR/config
           Repository specific configuration file.

       ~/.gitconfig
           User-specific configuration file. Also called "global" configuration file.

       $XDG_CONFIG_HOME/git/config
           Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty,
           $HOME/.config/git/config will be used. Any single-valued variable set in this file will be
           overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you
           sometimes use older versions of Git, as support for this file was added fairly recently.

       $(prefix)/etc/gitconfig
           System-wide configuration file.

       If no further options are given, all reading options will read all of these files that are available.
       If the global or the system-wide configuration file are not available they will be ignored. If the
       repository configuration file is not available or readable, git config will exit with a non-zero
       error code. However, in neither case will an error message be issued.

       All writing options will per default write to the repository specific configuration file. Note that
       this also affects options like --replace-all and --unset. git config will only ever change one file
       at a time.

       You can override these rules either by command line options or by environment variables. The --global
       and the --system options will limit the file used to the global or system-wide file respectively. The
       GIT_CONFIG environment variable has a similar effect, but you can specify any filename you want.

ENVIRONMENT
       GIT_CONFIG
           Take the configuration from the given file instead of .git/config. Using the "--global" option
           forces this to ~/.gitconfig. Using the "--system" option forces this to $(prefix)/etc/gitconfig.

       GIT_CONFIG_NOSYSTEM
           Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file. See git(1)
           for details.

       See also the section called "FILES".

EXAMPLES
       Given a .git/config like this:

           #
           # This is the config file, and
           # a '#' or ';' character indicates
           # a comment
           #

           ; core variables
           [core]
                   ; Don't trust file modes
                   filemode = false

           ; Our diff algorithm
           [diff]
                   external = /usr/local/bin/diff-wrapper
                   renames = true

           ; Proxy settings
           [core]
                   gitproxy=proxy-command for kernel.org
                   gitproxy=default-proxy ; for all the rest

       you can set the filemode to true with

           % git config core.filemode true


       The hypothetical proxy command entries actually have a postfix to discern what URL they apply to.
       Here is how to change the entry for kernel.org to "ssh".

           % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'


       This makes sure that only the key/value pair for kernel.org is replaced.

       To delete the entry for renames, do

           % git config --unset diff.renames


       If you want to delete an entry for a multivar (like core.gitproxy above), you have to provide a regex
       matching the value of exactly one line.

       To query the value for a given key, do

           % git config --get core.filemode


       or

           % git config core.filemode


       or, to query a multivar:

           % git config --get core.gitproxy "for kernel.org$"


       If you want to know all the values for a multivar, do:

           % git config --get-all core.gitproxy


       If you like to live dangerously, you can replace all core.gitproxy by a new one with

           % git config --replace-all core.gitproxy ssh


       However, if you really only want to replace the line for the default proxy, i.e. the one without a
       "for ..." postfix, do something like this:

           % git config core.gitproxy ssh '! for '


       To actually match only values with an exclamation mark, you have to

           % git config section.key value '[!]'


       To add a new proxy, without altering any of the existing ones, use

           % git config --add core.gitproxy '"proxy-command" for example.com'


       An example to use customized color from the configuration in your script:

           #!/bin/sh
           WS=$(git config --get-color color.diff.whitespace "blue reverse")
           RESET=$(git config --get-color "" "reset")
           echo "${WS}your whitespace color or blue reverse${RESET}"


CONFIGURATION FILE
       The Git configuration file contains a number of variables that affect the Git commands' behavior. The
       .git/config file in each repository is used to store the configuration for that repository, and
       $HOME/.gitconfig is used to store a per-user configuration as fallback values for the .git/config
       file. The file /etc/gitconfig can be used to store a system-wide default configuration.

       The configuration variables are used by both the Git plumbing and the porcelains. The variables are
       divided into sections, wherein the fully qualified variable name of the variable itself is the last
       dot-separated segment and the section name is everything before the last dot. The variable names are
       case-insensitive, allow only alphanumeric characters and -, and must start with an alphabetic
       character. Some variables may appear multiple times.

   Syntax
       The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The # and ; characters
       begin comments to the end of line, blank lines are ignored.

       The file consists of sections and variables. A section begins with the name of the section in square
       brackets and continues until the next section begins. Section names are not case sensitive. Only
       alphanumeric characters, - and . are allowed in section names. Each variable must belong to some
       section, which means that there must be a section header before the first setting of a variable.

       Sections can be further divided into subsections. To begin a subsection put its name in double
       quotes, separated by space from the section name, in the section header, like in the example below:

                   [section "subsection"]


       Subsection names are case sensitive and can contain any characters except newline (doublequote " and
       backslash have to be escaped as \" and \\, respectively). Section headers cannot span multiple lines.
       Variables may belong directly to a section or to a given subsection. You can have [section] if you
       have [section "subsection"], but you don't need to.

       There is also a deprecated [section.subsection] syntax. With this syntax, the subsection name is
       converted to lower-case and is also compared case sensitively. These subsection names follow the same
       restrictions as section names.

       All the other lines (and the remainder of the line after the section header) are recognized as
       setting variables, in the form name = value. If there is no equal sign on the line, the entire line
       is taken as name and the variable is recognized as boolean "true". The variable names are
       case-insensitive, allow only alphanumeric characters and -, and must start with an alphabetic
       character. There can be more than one value for a given variable; we say then that the variable is
       multivalued.

       Leading and trailing whitespace in a variable value is discarded. Internal whitespace within a
       variable value is retained verbatim.

       The values following the equals sign in variable assign are all either a string, an integer, or a
       boolean. Boolean values may be given as yes/no, 1/0, true/false or on/off. Case is not significant in
       boolean values, when converting value to the canonical form using --bool type specifier; git config
       will ensure that the output is "true" or "false".

       String values may be entirely or partially enclosed in double quotes. You need to enclose variable
       values in double quotes if you want to preserve leading or trailing whitespace, or if the variable
       value contains comment characters (i.e. it contains # or ;). Double quote " and backslash \
       characters in variable values must be escaped: use \" for " and \\ for \.

       The following escape sequences (beside \" and \\) are recognized: \n for newline character (NL), \t
       for horizontal tabulation (HT, TAB) and \b for backspace (BS). No other char escape sequence, nor
       octal char sequences are valid.

       Variable values ending in a \ are continued on the next line in the customary UNIX fashion.

       Some variables may require a special value format.

   Includes
       You can include one config file from another by setting the special include.path variable to the name
       of the file to be included. The included file is expanded immediately, as if its contents had been
       found at the location of the include directive. If the value of the include.path variable is a
       relative path, the path is considered to be relative to the configuration file in which the include
       directive was found. The value of include.path is subject to tilde expansion: ~/ is expanded to the
       value of $HOME, and ~user/ to the specified user's home directory. See below for examples.

   Example
           # Core variables
           [core]
                   ; Don't trust file modes
                   filemode = false

           # Our diff algorithm
           [diff]
                   external = /usr/local/bin/diff-wrapper
                   renames = true

           [branch "devel"]
                   remote = origin
                   merge = refs/heads/devel

           # Proxy settings
           [core]
                   gitProxy="ssh" for "kernel.org"
                   gitProxy=default-proxy ; for the rest

           [include]
                   path = /path/to/foo.inc ; include by absolute path
                   path = foo ; expand "foo" relative to the current file
                   path = ~/foo ; expand "foo" in your $HOME directory

   Variables
       Note that this list is non-comprehensive and not necessarily complete. For command-specific
       variables, you will find a more detailed description in the appropriate manual page. You will find a
       description of non-core porcelain configuration variables in the respective porcelain documentation.

       advice.*
           These variables control various optional help messages designed to aid new users. All advice.*
           variables default to true, and you can tell Git that you do not need help by setting these to
           false:

           pushUpdateRejected
               Set this variable to false if you want to disable pushNonFFCurrent, pushNonFFDefault,
               pushNonFFMatching, pushAlreadyExists, pushFetchFirst, and pushNeedsForce simultaneously.

           pushNonFFCurrent
               Advice shown when git-push(1) fails due to a non-fast-forward update to the current branch.

           pushNonFFDefault
               Advice to set push.default to upstream or current when you ran git-push(1) and pushed
               matching refs by default (i.e. you did not provide an explicit refspec, and no push.default
               configuration was set) and it resulted in a non-fast-forward error.

           pushNonFFMatching
               Advice shown when you ran git-push(1) and pushed matching refs explicitly (i.e. you used :,
               or specified a refspec that isn't your current branch) and it resulted in a non-fast-forward
               error.

           pushAlreadyExists
               Shown when git-push(1) rejects an update that does not qualify for fast-forwarding (e.g., a
               tag.)

           pushFetchFirst
               Shown when git-push(1) rejects an update that tries to overwrite a remote ref that points at
               an object we do not have.

           pushNeedsForce
               Shown when git-push(1) rejects an update that tries to overwrite a remote ref that points at
               an object that is not a committish, or make the remote ref point at an object that is not a
               committish.

           statusHints
               Show directions on how to proceed from the current state in the output of git-status(1), in
               the template shown when writing commit messages in git-commit(1), and in the help message
               shown by git-checkout(1) when switching branch.

           statusUoption
               Advise to consider using the -u option to git-status(1) when the command takes more than 2
               seconds to enumerate untracked files.

           commitBeforeMerge
               Advice shown when git-merge(1) refuses to merge to avoid overwriting local changes.

           resolveConflict
               Advice shown by various commands when conflicts prevent the operation from being performed.

           implicitIdentity
               Advice on how to set your identity configuration when your information is guessed from the
               system username and domain name.

           detachedHead
               Advice shown when you used git-checkout(1) to move to the detach HEAD state, to instruct how
               to create a local branch after the fact.

           amWorkDir
               Advice that shows the location of the patch file when git-am(1) fails to apply it.

       core.fileMode
           If false, the executable bit differences between the index and the working tree are ignored;
           useful on broken filesystems like FAT. See git-update-index(1).

           The default is true, except git-clone(1) or git-init(1) will probe and set core.fileMode false if
           appropriate when the repository is created.

       core.ignoreCygwinFSTricks
           This option is only used by Cygwin implementation of Git. If false, the Cygwin stat() and lstat()
           functions are used. This may be useful if your repository consists of a few separate directories
           joined in one hierarchy using Cygwin mount. If true, Git uses native Win32 API whenever it is
           possible and falls back to Cygwin functions only to handle symbol links. The native mode is more
           than twice faster than normal Cygwin l/stat() functions. True by default, unless core.filemode is
           true, in which case ignoreCygwinFSTricks is ignored as Cygwin's POSIX emulation is required to
           support core.filemode.

       core.ignorecase
           If true, this option enables various workarounds to enable Git to work better on filesystems that
           are not case sensitive, like FAT. For example, if a directory listing finds "makefile" when Git
           expects "Makefile", Git will assume it is really the same file, and continue to remember it as
           "Makefile".

           The default is false, except git-clone(1) or git-init(1) will probe and set core.ignorecase true
           if appropriate when the repository is created.

       core.precomposeunicode
           This option is only used by Mac OS implementation of Git. When core.precomposeunicode=true, Git
           reverts the unicode decomposition of filenames done by Mac OS. This is useful when sharing a
           repository between Mac OS and Linux or Windows. (Git for Windows 1.7.10 or higher is needed, or
           Git under cygwin 1.7). When false, file names are handled fully transparent by Git, which is
           backward compatible with older versions of Git.

       core.trustctime
           If false, the ctime differences between the index and the working tree are ignored; useful when
           the inode change time is regularly modified by something outside Git (file system crawlers and
           some backup systems). See git-update-index(1). True by default.

       core.checkstat
           Determines which stat fields to match between the index and work tree. The user can set this to
           default or minimal. Default (or explicitly default), is to check all fields, including the
           sub-second part of mtime and ctime.

       core.quotepath
           The commands that output paths (e.g.  ls-files, diff), when not given the -z option, will quote
           "unusual" characters in the pathname by enclosing the pathname in a double-quote pair and with
           backslashes the same way strings in C source code are quoted. If this variable is set to false,
           the bytes higher than 0x80 are not quoted but output as verbatim. Note that double quote,
           backslash and control characters are always quoted without -z regardless of the setting of this
           variable.

       core.eol
           Sets the line ending type to use in the working directory for files that have the text property
           set. Alternatives are lf, crlf and native, which uses the platform's native line ending. The
           default value is native. See gitattributes(5) for more information on end-of-line conversion.

       core.safecrlf
           If true, makes Git check if converting CRLF is reversible when end-of-line conversion is active.
           Git will verify if a command modifies a file in the work tree either directly or indirectly. For
           example, committing a file followed by checking out the same file should yield the original file
           in the work tree. If this is not the case for the current setting of core.autocrlf, Git will
           reject the file. The variable can be set to "warn", in which case Git will only warn about an
           irreversible conversion but continue the operation.

           CRLF conversion bears a slight chance of corrupting data. When it is enabled, Git will convert
           CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and
           CRLF before the commit cannot be recreated by Git. For text files this is the right thing to do:
           it corrects line endings such that we have only LF line endings in the repository. But for binary
           files that are accidentally classified as text the conversion can corrupt data.

           If you recognize such corruption early you can easily fix it by setting the conversion type
           explicitly in .gitattributes. Right after committing you still have the original file in your
           work tree and this file is not yet corrupted. You can explicitly tell Git that this file is
           binary and Git will handle the file appropriately.

           Unfortunately, the desired effect of cleaning up text files with mixed line endings and the
           undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are
           removed in an irreversible way. For text files this is the right thing to do because CRLFs are
           line endings, while for binary files converting CRLFs corrupts data.

           Note, this safety check does not mean that a checkout will generate a file identical to the
           original file for a different setting of core.eol and core.autocrlf, but only for the current
           one. For example, a text file with LF would be accepted with core.eol=lf and could later be
           checked out with core.eol=crlf, in which case the resulting file would contain CRLF, although the
           original file contained LF. However, in both work trees the line endings would be consistent,
           that is either all LF or all CRLF, but never mixed. A file with mixed line endings would be
           reported by the core.safecrlf mechanism.

       core.autocrlf
           Setting this variable to "true" is almost the same as setting the text attribute to "auto" on all
           files except that text files are not guaranteed to be normalized: files that contain CRLF in the
           repository will not be touched. Use this setting if you want to have CRLF line endings in your
           working directory even though the repository does not have normalized line endings. This variable
           can be set to input, in which case no output conversion is performed.

       core.symlinks
           If false, symbolic links are checked out as small plain files that contain the link text.  git-update-index(1) gitupdate-index(1)
           update-index(1) and git-add(1) will not change the recorded type to regular file. Useful on
           filesystems like FAT that do not support symbolic links.

           The default is true, except git-clone(1) or git-init(1) will probe and set core.symlinks false if
           appropriate when the repository is created.

       core.gitProxy
           A "proxy command" to execute (as command host port) instead of establishing direct connection to
           the remote server when using the Git protocol for fetching. If the variable value is in the
           "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified
           domain string. This variable may be set multiple times and is matched in the given order; the
           first match wins.

           Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies
           universally, without the special "for" handling).

           The special string none can be used as the proxy command to specify that no proxy be used for a
           given domain pattern. This is useful for excluding servers inside a firewall from proxy use,
           while defaulting to a common proxy for external domains.

       core.ignoreStat
           If true, commands which modify both the working tree and the index will mark the updated paths
           with the "assume unchanged" bit in the index. These marked files are then assumed to stay
           unchanged in the working tree, until you mark them otherwise manually - Git will not detect the
           file changes by lstat() calls. This is useful on systems where those are very slow, such as
           Microsoft Windows. See git-update-index(1). False by default.

       core.preferSymlinkRefs
           Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic
           links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link.

       core.bare
           If true this repository is assumed to be bare and has no working directory associated with it. If
           this is the case a number of commands that require a working directory will be disabled, such as
           git-add(1) or git-merge(1).

           This setting is automatically guessed by git-clone(1) or git-init(1) when the repository was
           created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false),
           while all other repositories are assumed to be bare (bare = true).

       core.worktree
           Set the path to the root of the working tree. This can be overridden by the GIT_WORK_TREE
           environment variable and the --work-tree command line option. The value can be an absolute path
           or relative to the path to the .git directory, which is either specified by --git-dir or GIT_DIR,
           or automatically discovered. If --git-dir or GIT_DIR is specified but none of --work-tree,
           GIT_WORK_TREE and core.worktree is specified, the current working directory is regarded as the
           top level of your working tree.

           Note that this variable is honored even when set in a configuration file in a ".git" subdirectory
           of a directory and its value differs from the latter directory (e.g. "/path/to/.git/config" has
           core.worktree set to "/different/path"), which is most likely a misconfiguration. Running Git
           commands in the "/path/to" directory will still use "/different/path" as the root of the work
           tree and can cause confusion unless you know what you are doing (e.g. you are creating a
           read-only snapshot of the same index to a location different from the repository's usual working
           tree).

       core.logAllRefUpdates
           Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>", by
           appending the new and old SHA-1, the date/time and the reason of the update, but only when the
           file exists. If this configuration variable is set to true, missing "$GIT_DIR/logs/<ref>" file is
           automatically created for branch heads (i.e. under refs/heads/), remote refs (i.e. under
           refs/remotes/), note refs (i.e. under refs/notes/), and the symbolic ref HEAD.

           This information can be used to determine what commit was the tip of a branch "2 days ago".

           This value is true by default in a repository that has a working directory associated with it,
           and false by default in a bare repository.

       core.repositoryFormatVersion
           Internal variable identifying the repository format and layout version.

       core.sharedRepository
           When group (or true), the repository is made shareable between several users in a group (making
           sure all the files and objects are group-writable). When all (or world or everybody), the
           repository will be readable by all users, additionally to being group-shareable. When umask (or
           false), Git will use permissions reported by umask(2). When _xxx, where _xxx is an octal number,
           files in the repository will have this mode value.  _xxx will override user's umask value
           (whereas the other options will only override requested parts of the user's umask value).
           Examples: _66_ will make the repo read/write-able for the owner and group, but inaccessible to
           others (equivalent to group unless umask is e.g.  __22).  _64_ is a repository that is
           group-readable but not group-writable. See git-init(1). False by default.

       core.warnAmbiguousRefs
           If true, Git will warn you if the ref name you passed it is ambiguous and might match multiple
           refs in the repository. True by default.

       core.compression
           An integer -1..9, indicating a default compression level. -1 is the zlib default. 0 means no
           compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If set, this provides a
           default to other compression variables, such as core.loosecompression and pack.compression.

       core.loosecompression
           An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is
           the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being
           slowest. If not set, defaults to core.compression. If that is not set, defaults to 1 (best
           speed).

       core.packedGitWindowSize
           Number of bytes of a pack file to map into memory in a single mapping operation. Larger window
           sizes may allow your system to process a smaller number of large pack files more quickly. Smaller
           window sizes will negatively affect performance due to increased calls to the operating system's
           memory manager, but may improve performance when accessing a large number of large pack files.

           Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1
           GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably
           do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.packedGitLimit
           Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access
           more than this many bytes at once to complete an operation it will unmap existing regions to
           reclaim virtual address space within the process.

           Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. This should be reasonable
           for all users/operating systems, except on the largest projects. You probably do not need to
           adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.deltaBaseCacheLimit
           Maximum number of bytes to reserve for caching base objects that may be referenced by multiple
           deltified objects. By storing the entire decompressed base objects in a cache Git is able to
           avoid unpacking and decompressing frequently used base objects multiple times.

           Default is 16 MiB on all platforms. This should be reasonable for all users/operating systems,
           except on the largest projects. You probably do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.bigFileThreshold
           Files larger than this size are stored deflated, without attempting delta compression. Storing
           large files without delta compression avoids excessive memory usage, at the slight expense of
           increased disk usage.

           Default is 512 MiB on all platforms. This should be reasonable for most projects as source code
           and other text files can still be delta compressed, but larger binary media files won't be.

           Common unit suffixes of k, m, or g are supported.

       core.excludesfile
           In addition to .gitignore (per-directory) and .git/info/exclude, Git looks into this file for
           patterns of files which are not meant to be tracked. "~/" is expanded to the value of $HOME and
           "~user/" to the specified user's home directory. Its default value is
           $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty,
           $HOME/.config/git/ignore is used instead. See gitignore(5).

       core.askpass
           Some commands (e.g. svn and http interfaces) that interactively ask for a password can be told to
           use an external program given via the value of this variable. Can be overridden by the
           GIT_ASKPASS environment variable. If not set, fall back to the value of the SSH_ASKPASS
           environment variable or, failing that, a simple password prompt. The external program shall be
           given a suitable prompt as command line argument and write the password on its STDOUT.

       core.attributesfile
           In addition to .gitattributes (per-directory) and .git/info/attributes, Git looks into this file
           for attributes (see gitattributes(5)). Path expansions are made the same way as for
           core.excludesfile. Its default value is $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is
           either not set or empty, $HOME/.config/git/attributes is used instead.

       core.editor
           Commands such as commit and tag that lets you edit messages by launching an editor uses the value
           of this variable when it is set, and the environment variable GIT_EDITOR is not set. See git-var(1). gitvar(1).
           var(1).

       core.commentchar
           Commands such as commit and tag that lets you edit messages consider a line that begins with this
           character commented, and removes them after the editor returns (default #).

       sequence.editor
           Text editor used by git rebase -i for editing the rebase instruction file. The value is meant to
           be interpreted by the shell when it is used. It can be overridden by the GIT_SEQUENCE_EDITOR
           environment variable. When not configured the default commit message editor is used instead.

       core.pager
           The command that Git will use to paginate output. Can be overridden with the GIT_PAGER
           environment variable. Note that Git sets the LESS environment variable to FRSX if it is unset
           when it runs the pager. One can change these settings by setting the LESS variable to some other
           value. Alternately, these settings can be overridden on a project or global basis by setting the
           core.pager option. Setting core.pager has no effect on the LESS environment variable behaviour
           above, so if you want to override Git's default settings this way, you need to be explicit. For
           example, to disable the S option in a backward compatible manner, set core.pager to less -+S.
           This will be passed to the shell by Git, which will translate the final command to LESS=FRSX less
           -+S.

       core.whitespace
           A comma separated list of common whitespace problems to notice.  git diff will use
           color.diff.whitespace to highlight them, and git apply --whitespace=error will consider them as
           errors. You can prefix - to disable any of them (e.g.  -trailing-space):

               blank-at-eol treats trailing whitespaces at the end of the line as an error (enabled by
               default).

               space-before-tab treats a space character that appears immediately before a tab character in
               the initial indent part of the line as an error (enabled by default).

               indent-with-non-tab treats a line that is indented with space characters instead of the
               equivalent tabs as an error (not enabled by default).

               tab-in-indent treats a tab character in the initial indent part of the line as an error (not
               enabled by default).

               blank-at-eof treats blank lines added at the end of file as an error (enabled by default).

               trailing-space is a short-hand to cover both blank-at-eol and blank-at-eof.

               cr-at-eol treats a carriage-return at the end of line as part of the line terminator, i.e.
               with it, trailing-space does not trigger if the character before such a carriage-return is
               not a whitespace (not enabled by default).

               tabwidth=<n> tells how many character positions a tab occupies; this is relevant for
               indent-with-non-tab and when Git fixes tab-in-indent errors. The default tab width is 8.
               Allowed values are 1 to 63.

       core.fsyncobjectfiles
           This boolean will enable fsync() when writing object files.

           This is a total waste of time and effort on a filesystem that orders data writes properly, but
           can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that
           only journal metadata and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").

       core.preloadindex
           Enable parallel index preload for operations like git diff

           This can speed up operations like git diff and git status especially on filesystems like NFS that
           have weak caching semantics and thus relatively high IO latencies. With this set to true, Git
           will do the index comparison to the filesystem data in parallel, allowing overlapping IO's.

       core.createObject
           You can set this to link, in which case a hardlink followed by a delete of the source are used to
           make sure that object creation will not overwrite existing objects.

           On some file system/operating system combinations, this is unreliable. Set this config setting to
           rename there; However, This will remove the check that makes sure that existing object files will
           not get overwritten.

       core.notesRef
           When showing commit messages, also show notes which are stored in the given ref. The ref must be
           fully qualified. If the given ref does not exist, it is not an error but means that no notes
           should be printed.

           This setting defaults to "refs/notes/commits", and it can be overridden by the GIT_NOTES_REF
           environment variable. See git-notes(1).

       core.sparseCheckout
           Enable "sparse checkout" feature. See section "Sparse checkout" in git-read-tree(1) for more
           information.

       core.abbrev
           Set the length object names are abbreviated to. If unspecified, many commands abbreviate to 7
           hexdigits, which may not be enough for abbreviated object names to stay unique for sufficiently
           long time.

       add.ignore-errors, add.ignoreErrors
           Tells git add to continue adding files when some files cannot be added due to indexing errors.
           Equivalent to the --ignore-errors option of git-add(1). Older versions of Git accept only
           add.ignore-errors, which does not follow the usual naming convention for configuration variables.
           Newer versions of Git honor add.ignoreErrors as well.

       alias.*
           Command aliases for the git(1) command wrapper - e.g. after defining "alias.last = cat-file
           commit HEAD", the invocation "git last" is equivalent to "git cat-file commit HEAD". To avoid
           confusion and troubles with script usage, aliases that hide existing Git commands are ignored.
           Arguments are split by spaces, the usual shell quoting and escaping is supported. quote pair and
           a backslash can be used to quote them.

           If the alias expansion is prefixed with an exclamation point, it will be treated as a shell
           command. For example, defining "alias.new = !gitk --all --not ORIG_HEAD", the invocation "git
           new" is equivalent to running the shell command "gitk --all --not ORIG_HEAD". Note that shell
           commands will be executed from the top-level directory of a repository, which may not necessarily
           be the current directory.  GIT_PREFIX is set as returned by running git rev-parse --show-prefix
           from the original current directory. See git-rev-parse(1).

       am.keepcr
           If true, git-am will call git-mailsplit for patches in mbox format with parameter --keep-cr. In
           this case git-mailsplit will not remove \r from lines ending with \r\n. Can be overridden by
           giving --no-keep-cr from the command line. See git-am(1), git-mailsplit(1).

       apply.ignorewhitespace
           When set to change, tells git apply to ignore changes in whitespace, in the same way as the
           --ignore-space-change option. When set to one of: no, none, never, false tells git apply to
           respect all whitespace differences. See git-apply(1).

       apply.whitespace
           Tells git apply how to handle whitespaces, in the same way as the --whitespace option. See git-apply(1). gitapply(1).
           apply(1).

       branch.autosetupmerge
           Tells git branch and git checkout to set up new branches so that git-pull(1) will appropriately
           merge from the starting point branch. Note that even if this option is not set, this behavior can
           be chosen per-branch using the --track and --no-track options. The valid settings are: false --no -no
           no automatic setup is done; true -- automatic setup is done when the starting point is a
           remote-tracking branch; always --  automatic setup is done when the starting point is either a
           local branch or remote-tracking branch. This option defaults to true.

       branch.autosetuprebase
           When a new branch is created with git branch or git checkout that tracks another branch, this
           variable tells Git to set up pull to rebase instead of merge (see "branch.<name>.rebase"). When
           never, rebase is never automatically set to true. When local, rebase is set to true for tracked
           branches of other local branches. When remote, rebase is set to true for tracked branches of
           remote-tracking branches. When always, rebase will be set to true for all tracking branches. See
           "branch.autosetupmerge" for details on how to set up a branch to track another branch. This
           option defaults to never.

       branch.<name>.remote
           When on branch <name>, it tells git fetch and git push which remote to fetch from/push to. The
           remote to push to may be overridden with remote.pushdefault (for all branches). The remote to
           push to, for the current branch, may be further overridden by branch.<name>.pushremote. If no
           remote is configured, or if you are not on any branch, it defaults to origin for fetching and
           remote.pushdefault for pushing.

       branch.<name>.pushremote
           When on branch <name>, it overrides branch.<name>.remote for pushing. It also overrides
           remote.pushdefault for pushing from branch <name>. When you pull from one place (e.g. your
           upstream) and push to another place (e.g. your own publishing repository), you would want to set
           remote.pushdefault to specify the remote to push to for all branches, and use this option to
           override it for a specific branch.

       branch.<name>.merge
           Defines, together with branch.<name>.remote, the upstream branch for the given branch. It tells
           git fetch/git pull/git rebase which branch to merge and can also affect git push (see
           push.default). When in branch <name>, it tells git fetch the default refspec to be marked for
           merging in FETCH_HEAD. The value is handled like the remote part of a refspec, and must match a
           ref which is fetched from the remote given by "branch.<name>.remote". The merge information is
           used by git pull (which at first calls git fetch) to lookup the default branch for merging.
           Without this option, git pull defaults to merge the first refspec fetched. Specify multiple
           values to get an octopus merge. If you wish to setup git pull so that it merges into <name> from
           another branch in the local repository, you can point branch.<name>.merge to the desired branch,
           and use the special setting .  (a period) for branch.<name>.remote.

       branch.<name>.mergeoptions
           Sets default options for merging into branch <name>. The syntax and supported options are the
           same as those of git-merge(1), but option values containing whitespace characters are currently
           not supported.

       branch.<name>.rebase
           When true, rebase the branch <name> on top of the fetched branch, instead of merging the default
           branch from the default remote when "git pull" is run. See "pull.rebase" for doing this in a non
           branch-specific manner.

           NOTE: this is a possibly dangerous operation; do not use it unless you understand the
           implications (see git-rebase(1) for details).

       branch.<name>.description
           Branch description, can be edited with git branch --edit-description. Branch description is
           automatically added in the format-patch cover letter or request-pull summary.

       browser.<tool>.cmd
           Specify the command to invoke the specified browser. The specified command is evaluated in shell
           with the URLs passed as arguments. (See git-web--browse(1).)

       browser.<tool>.path
           Override the path for the given tool that may be used to browse HTML help (see -w option in git-help(1)) githelp(1))
           help(1)) or a working repository in gitweb (see git-instaweb(1)).

       clean.requireForce
           A boolean to make git-clean do nothing unless given -f or -n. Defaults to true.

       color.branch
           A boolean to enable/disable color in the output of git-branch(1). May be set to always, false (or
           never) or auto (or true), in which case colors are used only when the output is to a terminal.
           Defaults to false.

       color.branch.<slot>
           Use customized color for branch coloration.  <slot> is one of current (the current branch), local
           (a local branch), remote (a remote-tracking branch in refs/remotes/), upstream (upstream tracking
           branch), plain (other refs).

           The value for these configuration variables is a list of colors (at most two) and attributes (at
           most one), separated by spaces. The colors accepted are normal, black, red, green, yellow, blue,
           magenta, cyan and white; the attributes are bold, dim, ul, blink and reverse. The first color
           given is the foreground; the second is the background. The position of the attribute, if any,
           doesn't matter.

       color.diff
           Whether to use ANSI escape sequences to add color to patches. If this is set to always, git-diff(1), gitdiff(1),
           diff(1), git-log(1), and git-show(1) will use color for all patches. If it is set to true or
           auto, those commands will only use color when output is to the terminal. Defaults to false.

           This does not affect git-format-patch(1) nor the git-diff-* plumbing commands. Can be overridden
           on the command line with the --color[=<when>] option.

       color.diff.<slot>
           Use customized color for diff colorization.  <slot> specifies which part of the patch to use the
           specified color, and is one of plain (context text), meta (metainformation), frag (hunk header),
           func (function in hunk header), old (removed lines), new (added lines), commit (commit headers),
           or whitespace (highlighting whitespace errors). The values of these variables may be specified as
           in color.branch.<slot>.

       color.decorate.<slot>
           Use customized color for git log --decorate output.  <slot> is one of branch, remoteBranch, tag,
           stash or HEAD for local branches, remote-tracking branches, tags, stash and HEAD, respectively.

       color.grep
           When set to always, always highlight matches. When false (or never), never. When set to true or
           auto, use color only when the output is written to the terminal. Defaults to false.

       color.grep.<slot>
           Use customized color for grep colorization.  <slot> specifies which part of the line to use the
           specified color, and is one of

           context
               non-matching text in context lines (when using -A, -B, or -C)

           filename
               filename prefix (when not using -h)

           function
               function name lines (when using -p)

           linenumber
               line number prefix (when using -n)

           match
               matching text

           selected
               non-matching text in selected lines

           separator
               separators between fields on a line (:, -, and =) and between hunks (--)

           The values of these variables may be specified as in color.branch.<slot>.

       color.interactive
           When set to always, always use colors for interactive prompts and displays (such as those used by
           "git-add --interactive"). When false (or never), never. When set to true or auto, use colors only
           when the output is to the terminal. Defaults to false.

       color.interactive.<slot>
           Use customized color for git add --interactive output.  <slot> may be prompt, header, help or
           error, for four distinct types of normal output from interactive commands. The values of these
           variables may be specified as in color.branch.<slot>.

       color.pager
           A boolean to enable/disable colored output when the pager is in use (default is true).

       color.showbranch
           A boolean to enable/disable color in the output of git-show-branch(1). May be set to always,
           false (or never) or auto (or true), in which case colors are used only when the output is to a
           terminal. Defaults to false.

       color.status
           A boolean to enable/disable color in the output of git-status(1). May be set to always, false (or
           never) or auto (or true), in which case colors are used only when the output is to a terminal.
           Defaults to false.

       color.status.<slot>
           Use customized color for status colorization.  <slot> is one of header (the header text of the
           status message), added or updated (files which are added but not committed), changed (files which
           are changed but not added in the index), untracked (files which are not tracked by Git), branch
           (the current branch), or nobranch (the color the no branch warning is shown in, defaulting to
           red). The values of these variables may be specified as in color.branch.<slot>.

       color.ui
           This variable determines the default value for variables such as color.diff and color.grep that
           control the use of color per command family. Its scope will expand as more commands learn
           configuration to set a default for the --color option. Set it to always if you want all output
           not intended for machine consumption to use color, to true or auto if you want such output to use
           color when written to the terminal, or to false or never if you prefer Git commands not to use
           color unless enabled explicitly with some other configuration or the --color option.

       column.ui
           Specify whether supported commands should output in columns. This variable consists of a list of
           tokens separated by spaces or commas:

           always
               always show in columns

           never
               never show in columns

           auto
               show in columns if the output is to the terminal

           column
               fill columns before rows (default)

           row
               fill rows before columns

           plain
               show in one column

           dense
               make unequal size columns to utilize more space

           nodense
               make equal size columns

           This option defaults to never.

       column.branch
           Specify whether to output branch listing in git branch in columns. See column.ui for details.

       column.status
           Specify whether to output untracked files in git status in columns. See column.ui for details.

       column.tag
           Specify whether to output tag listing in git tag in columns. See column.ui for details.

       commit.cleanup
           This setting overrides the default of the --cleanup option in git commit. See git-commit(1) for
           details. Changing the default can be useful when you always want to keep lines that begin with
           comment character # in your log message, in which case you would do git config commit.cleanup
           whitespace (note that you will have to remove the help lines that begin with # in the commit log
           template yourself, if you do this).

       commit.status
           A boolean to enable/disable inclusion of status information in the commit message template when
           using an editor to prepare the commit message. Defaults to true.

       commit.template
           Specify a file to use as the template for new commit messages. "~/" is expanded to the value of
           $HOME and "~user/" to the specified user's home directory.

       credential.helper
           Specify an external helper to be called when a username or password credential is needed; the
           helper may consult external storage to avoid prompting the user for the credentials. See
           gitcredentials(7) for details.

       credential.useHttpPath
           When acquiring credentials, consider the "path" component of an http or https URL to be
           important. Defaults to false. See gitcredentials(7) for more information.

       credential.username
           If no username is set for a network authentication, use this username by default. See
           credential.<context>.* below, and gitcredentials(7).

       credential.<url>.*
           Any of the credential.* options above can be applied selectively to some credentials. For example
           "credential.https://example.com.username" would set the default username only for https
           connections to example.com. See gitcredentials(7) for details on how URLs are matched.

       diff.autorefreshindex
           When using git diff to compare with work tree files, do not consider stat-only change as changed.
           Instead, silently run git update-index --refresh to update the cached stat information for paths
           whose contents in the work tree match the contents in the index. This option defaults to true.
           Note that this affects only git diff Porcelain, and not lower level diff commands such as git
           diff-files.

       diff.dirstat
           A comma separated list of --dirstat parameters specifying the default behavior of the --dirstat
           option to git-diff(1)` and friends. The defaults can be overridden on the command line (using
           --dirstat=<param1,param2,...>). The fallback defaults (when not changed by diff.dirstat) are
           changes,noncumulative,3. The following parameters are available:

           changes
               Compute the dirstat numbers by counting the lines that have been removed from the source, or
               added to the destination. This ignores the amount of pure code movements within a file. In
               other words, rearranging lines in a file is not counted as much as other changes. This is the
               default behavior when no parameter is given.

           lines
               Compute the dirstat numbers by doing the regular line-based diff analysis, and summing the
               removed/added line counts. (For binary files, count 64-byte chunks instead, since binary
               files have no natural concept of lines). This is a more expensive --dirstat behavior than the
               changes behavior, but it does count rearranged lines within a file as much as other changes.
               The resulting output is consistent with what you get from the other --*stat options.

           files
               Compute the dirstat numbers by counting the number of files changed. Each changed file counts
               equally in the dirstat analysis. This is the computationally cheapest --dirstat behavior,
               since it does not have to look at the file contents at all.

           cumulative
               Count changes in a child directory for the parent directory as well. Note that when using
               cumulative, the sum of the percentages reported may exceed 100%. The default (non-cumulative)
               behavior can be specified with the noncumulative parameter.

           <limit>
               An integer parameter specifies a cut-off percent (3% by default). Directories contributing
               less than this percentage of the changes are not shown in the output.

           Example: The following will count changed files, while ignoring directories with less than 10% of
           the total amount of changed files, and accumulating child directory counts in the parent
           directories: files,10,cumulative.

       diff.statGraphWidth
           Limit the width of the graph part in --stat output. If set, applies to all commands generating
           --stat output except format-patch.

       diff.context
           Generate diffs with <n> lines of context instead of the default of 3. This value is overridden by
           the -U option.

       diff.external
           If this config variable is set, diff generation is not performed using the internal diff
           machinery, but using the given command. Can be overridden with the `GIT_EXTERNAL_DIFF'
           environment variable. The command is called with parameters as described under "git Diffs" in
           git(1). Note: if you want to use an external diff program only on a subset of your files, you
           might want to use gitattributes(5) instead.

       diff.ignoreSubmodules
           Sets the default value of --ignore-submodules. Note that this affects only git diff Porcelain,
           and not lower level diff commands such as git diff-files.  git checkout also honors this setting
           when reporting uncommitted changes.

       diff.mnemonicprefix
           If set, git diff uses a prefix pair that is different from the standard "a/" and "b/" depending
           on what is being compared. When this configuration is in effect, reverse diff output also swaps
           the order of the prefixes:

           git diff
               compares the (i)ndex and the (w)ork tree;

           git diff HEAD
               compares a (c)ommit and the (w)ork tree;

           git diff --cached
               compares a (c)ommit and the (i)ndex;

           git diff HEAD:file1 file2
               compares an (o)bject and a (w)ork tree entity;

           git diff --no-index a b
               compares two non-git things (1) and (2).

       diff.noprefix
           If set, git diff does not show any source or destination prefix.

       diff.renameLimit
           The number of files to consider when performing the copy/rename detection; equivalent to the git
           diff option -l.

       diff.renames
           Tells Git to detect renames. If set to any boolean value, it will enable basic rename detection.
           If set to "copies" or "copy", it will detect copies, as well.

       diff.suppressBlankEmpty
           A boolean to inhibit the standard behavior of printing a space before each empty output line.
           Defaults to false.

       diff.submodule
           Specify the format in which differences in submodules are shown. The "log" format lists the
           commits in the range like git-submodule(1) summary does. The "short" format format just shows the
           names of the commits at the beginning and end of the range. Defaults to short.

       diff.wordRegex
           A POSIX Extended Regular Expression used to determine what is a "word" when performing
           word-by-word difference calculations. Character sequences that match the regular expression are
           "words", all other characters are ignorable whitespace.

       diff.<driver>.command
           The custom diff driver command. See gitattributes(5) for details.

       diff.<driver>.xfuncname
           The regular expression that the diff driver should use to recognize the hunk header. A built-in
           pattern may also be used. See gitattributes(5) for details.

       diff.<driver>.binary
           Set this option to true to make the diff driver treat files as binary. See gitattributes(5) for
           details.

       diff.<driver>.textconv
           The command that the diff driver should call to generate the text-converted version of a file.
           The result of the conversion is used to generate a human-readable diff. See gitattributes(5) for
           details.

       diff.<driver>.wordregex
           The regular expression that the diff driver should use to split words in a line. See
           gitattributes(5) for details.

       diff.<driver>.cachetextconv
           Set this option to true to make the diff driver cache the text conversion outputs. See
           gitattributes(5) for details.

       diff.tool
           Controls which diff tool is used by git-difftool(1). This variable overrides the value configured
           in merge.tool. The list below shows the valid built-in values. Any other value is treated as a
           custom diff tool and requires that a corresponding difftool.<tool>.cmd variable is defined.

       diff.algorithm
           Choose a diff algorithm. The variants are as follows:

           default, myers
               The basic greedy diff algorithm. Currently, this is the default.

           minimal
               Spend extra time to make sure the smallest possible diff is produced.

           patience
               Use "patience diff" algorithm when generating patches.

           histogram
               This algorithm extends the patience algorithm to "support low-occurrence common elements".

       difftool.<tool>.path
           Override the path for the given tool. This is useful in case your tool is not in the PATH.

       difftool.<tool>.cmd
           Specify the command to invoke the specified diff tool. The specified command is evaluated in
           shell with the following variables available: LOCAL is set to the name of the temporary file
           containing the contents of the diff pre-image and REMOTE is set to the name of the temporary file
           containing the contents of the diff post-image.

       difftool.prompt
           Prompt before each invocation of the diff tool.

       fetch.recurseSubmodules
           This option can be either set to a boolean value or to on-demand. Setting it to a boolean changes
           the behavior of fetch and pull to unconditionally recurse into submodules when set to true or to
           not recurse at all when set to false. When set to on-demand (the default value), fetch and pull
           will only recurse into a populated submodule when its superproject retrieves a commit that
           updates the submodule's reference.

       fetch.fsckObjects
           If it is set to true, git-fetch-pack will check all fetched objects. It will abort in the case of
           a malformed object or a broken link. The result of an abort are only dangling objects. Defaults
           to false. If not set, the value of transfer.fsckObjects is used instead.

       fetch.unpackLimit
           If the number of objects fetched over the Git native transfer is below this limit, then the
           objects will be unpacked into loose object files. However if the number of received objects
           equals or exceeds this limit then the received pack will be stored as a pack, after adding any
           missing delta bases. Storing the pack from a push can make the push operation complete faster,
           especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

       format.attach
           Enable multipart/mixed attachments as the default for format-patch. The value can also be a
           double quoted string which will enable attachments as the default and set the value as the
           boundary. See the --attach option in git-format-patch(1).

       format.numbered
           A boolean which can enable or disable sequence numbers in patch subjects. It defaults to "auto"
           which enables it only if there is more than one patch. It can be enabled or disabled for all
           messages by setting it to "true" or "false". See --numbered option in git-format-patch(1).

       format.headers
           Additional email headers to include in a patch to be submitted by mail. See git-format-patch(1).

       format.to, format.cc
           Additional recipients to include in a patch to be submitted by mail. See the --to and --cc
           options in git-format-patch(1).

       format.subjectprefix
           The default for format-patch is to output files with the [PATCH] subject prefix. Use this
           variable to change that prefix.

       format.signature
           The default for format-patch is to output a signature containing the Git version number. Use this
           variable to change that default. Set this variable to the empty string ("") to suppress signature
           generation.

       format.suffix
           The default for format-patch is to output files with the suffix .patch. Use this variable to
           change that suffix (make sure to include the dot if you want it).

       format.pretty
           The default pretty format for log/show/whatchanged command, See git-log(1), git-show(1), git-whatchanged(1). gitwhatchanged(1).
           whatchanged(1).

       format.thread
           The default threading style for git format-patch. Can be a boolean value, or shallow or deep.
           shallow threading makes every mail a reply to the head of the series, where the head is chosen
           from the cover letter, the --in-reply-to, and the first patch mail, in this order.  deep
           threading makes every mail a reply to the previous one. A true boolean value is the same as
           shallow, and a false value disables threading.

       format.signoff
           A boolean value which lets you enable the -s/--signoff option of format-patch by default.  Note:
           Adding the Signed-off-by: line to a patch should be a conscious act and means that you certify
           you have the rights to submit this work under the same open source license. Please see the
           SubmittingPatches document for further discussion.

       format.coverLetter
           A boolean that controls whether to generate a cover-letter when format-patch is invoked, but in
           addition can be set to "auto", to generate a cover-letter only when there's more than one patch.

       filter.<driver>.clean
           The command which is used to convert the content of a worktree file to a blob upon checkin. See
           gitattributes(5) for details.

       filter.<driver>.smudge
           The command which is used to convert the content of a blob object to a worktree file upon
           checkout. See gitattributes(5) for details.

       gc.aggressiveWindow
           The window size parameter used in the delta compression algorithm used by git gc --aggressive.
           This defaults to 250.

       gc.auto
           When there are approximately more than this many loose objects in the repository, git gc --auto
           will pack them. Some Porcelain commands use this command to perform a light-weight garbage
           collection from time to time. The default value is 6700. Setting this to 0 disables it.

       gc.autopacklimit
           When there are more than this many packs that are not marked with *.keep file in the repository,
           git gc --auto consolidates them into one larger pack. The default value is 50. Setting this to 0
           disables it.

       gc.packrefs
           Running git pack-refs in a repository renders it unclonable by Git versions prior to 1.5.1.2 over
           dumb transports such as HTTP. This variable determines whether git gc runs git pack-refs. This
           can be set to notbare to enable it within all non-bare repos or it can be set to a boolean value.
           The default is true.

       gc.pruneexpire
           When git gc is run, it will call prune --expire 2.weeks.ago. Override the grace period with this
           config variable. The value "now" may be used to disable this grace period and always prune
           unreachable objects immediately.

       gc.reflogexpire, gc.<pattern>.reflogexpire

           git reflog expire removes reflog entries older than this time; defaults to 90 days. With
           "<pattern>" (e.g. "refs/stash") in the middle the setting applies only to the refs that match the
           <pattern>.

       gc.reflogexpireunreachable, gc.<ref>.reflogexpireunreachable

           git reflog expire removes reflog entries older than this time and are not reachable from the
           current tip; defaults to 30 days. With "<pattern>" (e.g. "refs/stash") in the middle, the setting
           applies only to the refs that match the <pattern>.

       gc.rerereresolved
           Records of conflicted merge you resolved earlier are kept for this many days when git rerere gc
           is run. The default is 60 days. See git-rerere(1).

       gc.rerereunresolved
           Records of conflicted merge you have not resolved are kept for this many days when git rerere gc
           is run. The default is 15 days. See git-rerere(1).

       gitcvs.commitmsgannotation
           Append this string to each commit message. Set to empty string to disable this feature. Defaults
           to "via git-CVS emulator".

       gitcvs.enabled
           Whether the CVS server interface is enabled for this repository. See git-cvsserver(1).

       gitcvs.logfile
           Path to a log file where the CVS server interface well... logs various stuff. See git-cvsserver(1). gitcvsserver(1).
           cvsserver(1).

       gitcvs.usecrlfattr
           If true, the server will look up the end-of-line conversion attributes for files to determine the
           -k modes to use. If the attributes force Git to treat a file as text, the -k mode will be left
           blank so CVS clients will treat it as text. If they suppress text conversion, the file will be
           set with -kb mode, which suppresses any newline munging the client might otherwise do. If the
           attributes do not allow the file type to be determined, then gitcvs.allbinary is used. See
           gitattributes(5).

       gitcvs.allbinary
           This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If true, all
           unresolved files are sent to the client in mode -kb. This causes the client to treat them as
           binary files, which suppresses any newline munging it otherwise might do. Alternatively, if it is
           set to "guess", then the contents of the file are examined to decide if it is binary, similar to
           core.autocrlf.

       gitcvs.dbname
           Database used by git-cvsserver to cache revision information derived from the Git repository. The
           exact meaning depends on the used database driver, for SQLite (which is the default driver) this
           is a filename. Supports variable substitution (see git-cvsserver(1) for details). May not contain
           semicolons (;). Default: %Ggitcvs.%m.sqlite

       gitcvs.dbdriver
           Used Perl DBI driver. You can specify any available driver for this here, but it might not work.
           git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and reported not to work
           with DBD::mysql. Experimental feature. May not contain double colons (:). Default: SQLite. See
           git-cvsserver(1).

       gitcvs.dbuser, gitcvs.dbpass
           Database user and password. Only useful if setting gitcvs.dbdriver, since SQLite has no concept
           of database users and/or passwords.  gitcvs.dbuser supports variable substitution (see git-cvsserver(1) gitcvsserver(1)
           cvsserver(1) for details).

       gitcvs.dbTableNamePrefix
           Database table name prefix. Prepended to the names of any database tables used, allowing a single
           database to be used for several repositories. Supports variable substitution (see git-cvsserver(1) gitcvsserver(1)
           cvsserver(1) for details). Any non-alphabetic characters will be replaced with underscores.

       All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allbinary can also be specified as
       gitcvs.<access_method>.<varname> (where access_method is one of "ext" and "pserver") to make them
       apply only for the given access method.

       gitweb.category, gitweb.description, gitweb.owner, gitweb.url
           See gitweb(1) for description.

       gitweb.avatar, gitweb.blame, gitweb.grep, gitweb.highlight, gitweb.patches, gitweb.pickaxe,
       gitweb.remote_heads, gitweb.showsizes, gitweb.snapshot
           See gitweb.conf(5) for description.

       grep.lineNumber
           If set to true, enable -n option by default.

       grep.patternType
           Set the default matching behavior. Using a value of basic, extended, fixed, or perl will enable
           the --basic-regexp, --extended-regexp, --fixed-strings, or --perl-regexp option accordingly,
           while the value default will return to the default matching behavior.

       grep.extendedRegexp
           If set to true, enable --extended-regexp option by default. This option is ignored when the
           grep.patternType option is set to a value other than default.

       gpg.program
           Use this custom program instead of "gpg" found on $PATH when making or verifying a PGP signature.
           The program must support the same command line interface as GPG, namely, to verify a detached
           signature, "gpg --verify $file - <$signature" is run, and the program is expected to signal a
           good signature by exiting with code 0, and to generate an ascii-armored detached signature, the
           standard input of "gpg -bsau $key" is fed with the contents to be signed, and the program is
           expected to send the result to its standard output.

       gui.commitmsgwidth
           Defines how wide the commit message window is in the git-gui(1). "75" is the default.

       gui.diffcontext
           Specifies how many context lines should be used in calls to diff made by the git-gui(1). The
           default is "5".

       gui.encoding
           Specifies the default encoding to use for displaying of file contents in git-gui(1) and gitk(1).
           It can be overridden by setting the encoding attribute for relevant files (see gitattributes(5)).
           If this option is not set, the tools default to the locale encoding.

       gui.matchtrackingbranch
           Determines if new branches created with git-gui(1) should default to tracking remote branches
           with matching names or not. Default: "false".

       gui.newbranchtemplate
           Is used as suggested name when creating new branches using the git-gui(1).

       gui.pruneduringfetch
           "true" if git-gui(1) should prune remote-tracking branches when performing a fetch. The default
           value is "false".

       gui.trustmtime
           Determines if git-gui(1) should trust the file modification timestamp or not. By default the
           timestamps are not trusted.

       gui.spellingdictionary
           Specifies the dictionary used for spell checking commit messages in the git-gui(1). When set to
           "none" spell checking is turned off.

       gui.fastcopyblame
           If true, git gui blame uses -C instead of -C -C for original location detection. It makes blame
           significantly faster on huge repositories at the expense of less thorough copy detection.

       gui.copyblamethreshold
           Specifies the threshold to use in git gui blame original location detection, measured in
           alphanumeric characters. See the git-blame(1) manual for more information on copy detection.

       gui.blamehistoryctx
           Specifies the radius of history context in days to show in gitk(1) for the selected commit, when
           the Show History Context menu item is invoked from git gui blame. If this variable is set to
           zero, the whole history is shown.

       guitool.<name>.cmd
           Specifies the shell command line to execute when the corresponding item of the git-gui(1) Tools
           menu is invoked. This option is mandatory for every tool. The command is executed from the root
           of the working directory, and in the environment it receives the name of the tool as GIT_GUITOOL,
           the name of the currently selected file as FILENAME, and the name of the current branch as
           CUR_BRANCH (if the head is detached, CUR_BRANCH is empty).

       guitool.<name>.needsfile
           Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not empty.

       guitool.<name>.noconsole
           Run the command silently, without creating a window to display its output.

       guitool.<name>.norescan
           Don't rescan the working directory for changes after the tool finishes execution.

       guitool.<name>.confirm
           Show a confirmation dialog before actually running the tool.

       guitool.<name>.argprompt
           Request a string argument from the user, and pass it to the tool through the ARGS environment
           variable. Since requesting an argument implies confirmation, the confirm option has no effect if
           this is enabled. If the option is set to true, yes, or 1, the dialog uses a built-in generic
           prompt; otherwise the exact value of the variable is used.

       guitool.<name>.revprompt
           Request a single valid revision from the user, and set the REVISION environment variable. In
           other aspects this option is similar to argprompt, and can be used together with it.

       guitool.<name>.revunmerged
           Show only unmerged branches in the revprompt subdialog. This is useful for tools similar to merge
           or rebase, but not for things like checkout or reset.

       guitool.<name>.title
           Specifies the title to use for the prompt dialog. The default is the tool name.

       guitool.<name>.prompt
           Specifies the general prompt string to display at the top of the dialog, before subsections for
           argprompt and revprompt. The default value includes the actual command.

       help.browser
           Specify the browser that will be used to display help in the web format. See git-help(1).

       help.format
           Override the default help format used by git-help(1). Values man, info, web and html are
           supported.  man is the default.  web and html are the same.

       help.autocorrect
           Automatically correct and execute mistyped commands after waiting for the given number of
           deciseconds (0.1 sec). If more than one command can be deduced from the entered text, nothing
           will be executed. If the value of this option is negative, the corrected command will be executed
           immediately. If the value is 0 - the command will be just shown but not executed. This is the
           default.

       help.htmlpath
           Specify the path where the HTML documentation resides. File system paths and URLs are supported.
           HTML pages will be prefixed with this path when help is displayed in the web format. This
           defaults to the documentation path of your Git installation.

       http.proxy
           Override the HTTP proxy, normally configured using the http_proxy, https_proxy, and all_proxy
           environment variables (see curl(1)). This can be overridden on a per-remote basis; see
           remote.<name>.proxy

       http.cookiefile
           File containing previously stored cookie lines which should be used in the Git http session, if
           they match the server. The file format of the file to read cookies from should be plain HTTP
           headers or the Netscape/Mozilla cookie file format (see curl(1)). NOTE that the file specified
           with http.cookiefile is only used as input. No cookies will be stored in the file.

       http.sslVerify
           Whether to verify the SSL certificate when fetching or pushing over HTTPS. Can be overridden by
           the GIT_SSL_NO_VERIFY environment variable.

       http.sslCert
           File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the
           GIT_SSL_CERT environment variable.

       http.sslKey
           File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the
           GIT_SSL_KEY environment variable.

       http.sslCertPasswordProtected
           Enable Git's password prompt for the SSL certificate. Otherwise OpenSSL will prompt the user,
           possibly many times, if the certificate or private key is encrypted. Can be overridden by the
           GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

       http.sslCAInfo
           File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can
           be overridden by the GIT_SSL_CAINFO environment variable.

       http.sslCAPath
           Path containing files with the CA certificates to verify the peer with when fetching or pushing
           over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

       http.sslTry
           Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular FTP
           protocol. This might be needed if the FTP server requires it for security reasons or you wish to
           connect securely whenever remote FTP server supports it. Default is false since it might trigger
           certificate verification errors on misconfigured servers.

       http.maxRequests
           How many HTTP requests to launch in parallel. Can be overridden by the GIT_HTTP_MAX_REQUESTS
           environment variable. Default is 5.

       http.minSessions
           The number of curl sessions (counted across slots) to be kept across requests. They will not be
           ended with curl_easy_cleanup() until http_cleanup() is invoked. If USE_CURL_MULTI is not defined,
           this value will be capped at 1. Defaults to 1.

       http.postBuffer
           Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote
           system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is
           used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for
           most requests.

       http.lowSpeedLimit, http.lowSpeedTime
           If the HTTP transfer speed is less than http.lowSpeedLimit for longer than http.lowSpeedTime
           seconds, the transfer is aborted. Can be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and
           GIT_HTTP_LOW_SPEED_TIME environment variables.

       http.noEPSV
           A boolean which disables using of EPSV ftp command by curl. This can helpful with some "poor" ftp
           servers which don't support EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment
           variable. Default is false (curl will use EPSV).

       http.useragent
           The HTTP USER_AGENT string presented to an HTTP server. The default value represents the version
           of the client Git such as git/1.7.1. This option allows you to override this value to a more
           common value such as Mozilla/4.0. This may be necessary, for instance, if connecting through a
           firewall that restricts HTTP connections to a set of common USER_AGENT strings (but not including
           those like git/1.7.1). Can be overridden by the GIT_HTTP_USER_AGENT environment variable.

       i18n.commitEncoding
           Character encoding the commit messages are stored in; Git itself does not care per se, but this
           information is necessary e.g. when importing commits from emails or in the gitk graphical history
           browser (and possibly at other places in the future or in other porcelains). See e.g.  git-mailinfo(1). gitmailinfo(1).
           mailinfo(1). Defaults to utf-8.

       i18n.logOutputEncoding
           Character encoding the commit messages are converted to when running git log and friends.

       imap
           The configuration variables in the imap section are described in git-imap-send(1).

       init.templatedir
           Specify the directory from which templates will be copied. (See the "TEMPLATE DIRECTORY" section
           of git-init(1).)

       instaweb.browser
           Specify the program that will be used to browse your working repository in gitweb. See git-instaweb(1). gitinstaweb(1).
           instaweb(1).

       instaweb.httpd
           The HTTP daemon command-line to start gitweb on your working repository. See git-instaweb(1).

       instaweb.local
           If true the web server started by git-instaweb(1) will be bound to the local IP (127.0.0.1).

       instaweb.modulepath
           The default module path for git-instaweb(1) to use instead of /usr/lib/apache2/modules. Only used
           if httpd is Apache.

       instaweb.port
           The port number to bind the gitweb httpd to. See git-instaweb(1).

       interactive.singlekey
           In interactive commands, allow the user to provide one-letter input with a single key (i.e.,
           without hitting enter). Currently this is used by the --patch mode of git-add(1), git-checkout(1), gitcheckout(1),
           checkout(1), git-commit(1), git-reset(1), and git-stash(1). Note that this setting is silently
           ignored if portable keystroke input is not available.

       log.abbrevCommit
           If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --abbrev-commit. You may
           override this option with --no-abbrev-commit.

       log.date
           Set the default date-time mode for the log command. Setting a value for log.date is similar to
           using git log's --date option. Possible values are relative, local, default, iso, rfc, and short;
           see git-log(1) for details.

       log.decorate
           Print out the ref names of any commits that are shown by the log command. If short is specified,
           the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be printed. If full is
           specified, the full ref name (including prefix) will be printed. This is the same as the log
           commands --decorate option.

       log.showroot
           If true, the initial commit will be shown as a big creation event. This is equivalent to a diff
           against an empty tree. Tools like git-log(1) or git-whatchanged(1), which normally hide the root
           commit will now show it. True by default.

       log.mailmap
           If true, makes git-log(1), git-show(1), and git-whatchanged(1) assume --use-mailmap.

       mailmap.file
           The location of an augmenting mailmap file. The default mailmap, located in the root of the
           repository, is loaded first, then the mailmap file pointed to by this variable. The location of
           the mailmap file may be in a repository subdirectory, or somewhere outside of the repository
           itself. See git-shortlog(1) and git-blame(1).

       mailmap.blob
           Like mailmap.file, but consider the value as a reference to a blob in the repository. If both
           mailmap.file and mailmap.blob are given, both are parsed, with entries from mailmap.file taking
           precedence. In a bare repository, this defaults to HEAD:.mailmap. In a non-bare repository, it
           defaults to empty.

       man.viewer
           Specify the programs that may be used to display help in the man format. See git-help(1).

       man.<tool>.cmd
           Specify the command to invoke the specified man viewer. The specified command is evaluated in
           shell with the man page passed as argument. (See git-help(1).)

       man.<tool>.path
           Override the path for the given tool that may be used to display help in the man format. See git-help(1). githelp(1).
           help(1).

       merge.conflictstyle
           Specify the style in which conflicted hunks are written out to working tree files upon merge. The
           default is "merge", which shows a <<<<<<< conflict marker, changes made by one side, a =======
           marker, changes made by the other side, and then a >>>>>>> marker. An alternate style, "diff3",
           adds a ||||||| marker and the original text before the ======= marker.

       merge.defaultToUpstream
           If merge is called without any commit argument, merge the upstream branches configured for the
           current branch by using their last observed values stored in their remote-tracking branches. The
           values of the branch.<current branch>.merge that name the branches at the remote named by
           branch.<current branch>.remote are consulted, and then they are mapped via remote.<remote>.fetch
           to their corresponding remote-tracking branches, and the tips of these tracking branches are
           merged.

       merge.ff
           By default, Git does not create an extra merge commit when merging a commit that is a descendant
           of the current commit. Instead, the tip of the current branch is fast-forwarded. When set to
           false, this variable tells Git to create an extra merge commit in such a case (equivalent to
           giving the --no-ff option from the command line). When set to only, only such fast-forward merges
           are allowed (equivalent to giving the --ff-only option from the command line).

       merge.log
           In addition to branch names, populate the log message with at most the specified number of
           one-line descriptions from the actual commits that are being merged. Defaults to false, and true
           is a synonym for 20.

       merge.renameLimit
           The number of files to consider when performing rename detection during a merge; if not
           specified, defaults to the value of diff.renameLimit.

       merge.renormalize
           Tell Git that canonical representation of files in the repository has changed over time (e.g.
           earlier commits record text files with CRLF line endings, but recent ones use LF line endings).
           In such a repository, Git can convert the data recorded in commits to a canonical form before
           performing a merge to reduce unnecessary conflicts. For more information, see section "Merging
           branches with differing checkin/checkout attributes" in gitattributes(5).

       merge.stat
           Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the merge.
           True by default.

       merge.tool
           Controls which merge tool is used by git-mergetool(1). The list below shows the valid built-in
           values. Any other value is treated as a custom merge tool and requires that a corresponding
           mergetool.<tool>.cmd variable is defined.

              araxis

              bc3

              codecompare

              deltawalker

              vimdiff

              vimdiff2

              xxdiff

       merge.verbosity
           Controls the amount of output shown by the recursive merge strategy. Level 0 outputs nothing
           except a final error message if conflicts were detected. Level 1 outputs only conflicts, 2
           outputs conflicts and file changes. Level 5 and above outputs debugging information. The default
           is level 2. Can be overridden by the GIT_MERGE_VERBOSITY environment variable.

       merge.<driver>.name
           Defines a human-readable name for a custom low-level merge driver. See gitattributes(5) for
           details.

       merge.<driver>.driver
           Defines the command that implements a custom low-level merge driver. See gitattributes(5) for
           details.

       merge.<driver>.recursive
           Names a low-level merge driver to be used when performing an internal merge between common
           ancestors. See gitattributes(5) for details.

       mergetool.<tool>.path
           Override the path for the given tool. This is useful in case your tool is not in the PATH.

       mergetool.<tool>.cmd
           Specify the command to invoke the specified merge tool. The specified command is evaluated in
           shell with the following variables available: BASE is the name of a temporary file containing the
           common base of the files to be merged, if available; LOCAL is the name of a temporary file
           containing the contents of the file on the current branch; REMOTE is the name of a temporary file
           containing the contents of the file from the branch being merged; MERGED contains the name of the
           file to which the merge tool should write the results of a successful merge.

       mergetool.<tool>.trustExitCode
           For a custom merge command, specify whether the exit code of the merge command can be used to
           determine whether the merge was successful. If this is not set to true then the merge target file
           timestamp is checked and the merge assumed to have been successful if the file has been updated,
           otherwise the user is prompted to indicate the success of the merge.

       mergetool.keepBackup
           After performing a merge, the original file with conflict markers can be saved as a file with a
           .orig extension. If this variable is set to false then this file is not preserved. Defaults to
           true (i.e. keep the backup files).

       mergetool.keepTemporaries
           When invoking a custom merge tool, Git uses a set of temporary files to pass to the tool. If the
           tool returns an error and this variable is set to true, then these temporary files will be
           preserved, otherwise they will be removed after the tool has exited. Defaults to false.

       mergetool.prompt
           Prompt before each invocation of the merge resolution program.

       notes.displayRef
           The (fully qualified) refname from which to show notes when showing commit messages. The value of
           this variable can be set to a glob, in which case notes from all matching refs will be shown. You
           may also specify this configuration variable several times. A warning will be issued for refs
           that do not exist, but a glob that does not match any refs is silently ignored.

           This setting can be overridden with the GIT_NOTES_DISPLAY_REF environment variable, which must be
           a colon separated list of refs or globs.

           The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also implicitly
           added to the list of refs to be displayed.

       notes.rewrite.<command>
           When rewriting commits with <command> (currently amend or rebase) and this variable is set to
           true, Git automatically copies your notes from the original to the rewritten commit. Defaults to
           true, but see "notes.rewriteRef" below.

       notes.rewriteMode
           When copying notes during a rewrite (see the "notes.rewrite.<command>" option), determines what
           to do if the target commit already has a note. Must be one of overwrite, concatenate, or ignore.
           Defaults to concatenate.

           This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.

       notes.rewriteRef
           When copying notes during a rewrite, specifies the (fully qualified) ref whose notes should be
           copied. The ref may be a glob, in which case notes in all matching refs will be copied. You may
           also specify this configuration several times.

           Does not have a default value; you must configure this variable to enable note rewriting. Set it
           to refs/notes/commits to enable rewriting for the default commit notes.

           This setting can be overridden with the GIT_NOTES_REWRITE_REF environment variable, which must be
           a colon separated list of refs or globs.

       pack.window
           The size of the window used by git-pack-objects(1) when no window size is given on the command
           line. Defaults to 10.

       pack.depth
           The maximum delta depth used by git-pack-objects(1) when no maximum depth is given on the command
           line. Defaults to 50.

       pack.windowMemory
           The window memory size limit used by git-pack-objects(1) when no limit is given on the command
           line. The value can be suffixed with "k", "m", or "g". Defaults to 0, meaning no limit.

       pack.compression
           An integer -1..9, indicating the compression level for objects in a pack file. -1 is the zlib
           default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If
           not set, defaults to core.compression. If that is not set, defaults to -1, the zlib default,
           which is "a default compromise between speed and compression (currently equivalent to level 6)."

           Note that changing the compression level will not automatically recompress all existing objects.
           You can force recompression by passing the -F option to git-repack(1).

       pack.deltaCacheSize
           The maximum memory in bytes used for caching deltas in git-pack-objects(1) before writing them
           out to a pack. This cache is used to speed up the writing object phase by not having to recompute
           the final delta result once the best match for all objects is found. Repacking large repositories
           on machines which are tight with memory might be badly impacted by this though, especially if
           this cache pushes the system into swapping. A value of 0 means no limit. The smallest size of 1
           byte may be used to virtually disable this cache. Defaults to 256 MiB.

       pack.deltaCacheLimit
           The maximum size of a delta, that is cached in git-pack-objects(1). This cache is used to speed
           up the writing object phase by not having to recompute the final delta result once the best match
           for all objects is found. Defaults to 1000.

       pack.threads
           Specifies the number of threads to spawn when searching for best delta matches. This requires
           that git-pack-objects(1) be compiled with pthreads otherwise this option is ignored with a
           warning. This is meant to reduce packing time on multiprocessor machines. The required amount of
           memory for the delta search window is however multiplied by the number of threads. Specifying 0
           will cause Git to auto-detect the number of CPU's and set the number of threads accordingly.

       pack.indexVersion
           Specify the default pack index version. Valid values are 1 for legacy pack index used by Git
           versions prior to 1.5.2, and 2 for the new pack index with capabilities for packs larger than 4
           GB as well as proper protection against the repacking of corrupted packs. Version 2 is the
           default. Note that version 2 is enforced and this config option ignored whenever the
           corresponding pack is larger than 2 GB.

           If you have an old Git that does not understand the version 2 *.idx file, cloning or fetching
           over a non native protocol (e.g. "http" and "rsync") that will copy both *.pack file and
           corresponding *.idx file from the other side may give you a repository that cannot be accessed
           with your older version of Git. If the *.pack file is smaller than 2 GB, however, you can use
           git-index-pack(1) on the *.pack file to regenerate the *.idx file.

       pack.packSizeLimit
           The maximum size of a pack. This setting only affects packing to a file when repacking, i.e. the
           git:// protocol is unaffected. It can be overridden by the --max-pack-size option of git-repack(1). gitrepack(1).
           repack(1). The minimum size allowed is limited to 1 MiB. The default is unlimited. Common unit
           suffixes of k, m, or g are supported.

       pager.<cmd>
           If the value is boolean, turns on or off pagination of the output of a particular Git subcommand
           when writing to a tty. Otherwise, turns on pagination for the subcommand using the pager
           specified by the value of pager.<cmd>. If --paginate or --no-pager is specified on the command
           line, it takes precedence over this option. To disable pagination for all commands, set
           core.pager or GIT_PAGER to cat.

       pretty.<name>
           Alias for a --pretty= format string, as specified in git-log(1). Any aliases defined here can be
           used just as the built-in pretty formats could. For example, running git config pretty.changelog
           "format:* %H %s" would cause the invocation git log --pretty=changelog to be equivalent to
           running git log "--pretty=format:* %H %s". Note that an alias with the same name as a built-in
           format will be silently ignored.

       pull.rebase
           When true, rebase branches on top of the fetched branch, instead of merging the default branch
           from the default remote when "git pull" is run. See "branch.<name>.rebase" for setting this on a
           per-branch basis.

           NOTE: this is a possibly dangerous operation; do not use it unless you understand the
           implications (see git-rebase(1) for details).

       pull.octopus
           The default merge strategy to use when pulling multiple branches at once.

       pull.twohead
           The default merge strategy to use when pulling a single branch.

       push.default
           Defines the action git push should take if no refspec is given on the command line, no refspec is
           configured in the remote, and no refspec is implied by any of the options given on the command
           line. Possible values are:

               nothing - do not push anything.

               matching - push all branches having the same name in both ends. This is for those who
               prepare all the branches into a publishable shape and then push them out with a single
               command. It is not appropriate for pushing into a repository shared by multiple users, since
               locally stalled branches will attempt a non-fast forward push if other users updated the
               branch.

               This is currently the default, but Git 2.0 will change the default to simple.

               upstream - push the current branch to its upstream branch (tracking is a deprecated synonym
               for this). With this, git push will update the same remote ref as the one which is merged by
               git pull, making push and pull symmetrical. See "branch.<name>.merge" for how to configure
               the upstream branch.

               simple - like upstream, but refuses to push if the upstream branch's name is different from
               the local one. This is the safest option and is well-suited for beginners. It will become the
               default in Git 2.0.

               current - push the current branch to a branch of the same name.

           The simple, current and upstream modes are for those who want to push out a single branch after
           finishing work, even when the other branches are not yet ready to be pushed out. If you are
           working with other people to push into the same shared repository, you would want to use one of
           these.

       rebase.stat
           Whether to show a diffstat of what changed upstream since the last rebase. False by default.

       rebase.autosquash
           If set to true enable --autosquash option by default.

       receive.autogc
           By default, git-receive-pack will run "git-gc --auto" after receiving data from git-push and
           updating refs. You can stop it by setting this variable to false.

       receive.fsckObjects
           If it is set to true, git-receive-pack will check all received objects. It will abort in the case
           of a malformed object or a broken link. The result of an abort are only dangling objects.
           Defaults to false. If not set, the value of transfer.fsckObjects is used instead.

       receive.unpackLimit
           If the number of objects received in a push is below this limit then the objects will be unpacked
           into loose object files. However if the number of received objects equals or exceeds this limit
           then the received pack will be stored as a pack, after adding any missing delta bases. Storing
           the pack from a push can make the push operation complete faster, especially on slow filesystems.
           If not set, the value of transfer.unpackLimit is used instead.

       receive.denyDeletes
           If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this to prevent
           such a ref deletion via a push.

       receive.denyDeleteCurrent
           If set to true, git-receive-pack will deny a ref update that deletes the currently checked out
           branch of a non-bare repository.

       receive.denyCurrentBranch
           If set to true or "refuse", git-receive-pack will deny a ref update to the currently checked out
           branch of a non-bare repository. Such a push is potentially dangerous because it brings the HEAD
           out of sync with the index and working tree. If set to "warn", print a warning of such a push to
           stderr, but allow the push to proceed. If set to false or "ignore", allow such pushes with no
           message. Defaults to "refuse".

       receive.denyNonFastForwards
           If set to true, git-receive-pack will deny a ref update which is not a fast-forward. Use this to
           prevent such an update via a push, even if that push is forced. This configuration variable is
           set when initializing a shared repository.

       receive.hiderefs
           String(s) receive-pack uses to decide which refs to omit from its initial advertisement. Use more
           than one definitions to specify multiple prefix strings. A ref that are under the hierarchies
           listed on the value of this variable is excluded, and is hidden when responding to git push, and
           an attempt to update or delete a hidden ref by git push is rejected.

       receive.updateserverinfo
           If set to true, git-receive-pack will run git-update-server-info after receiving data from
           git-push and updating refs.

       remote.pushdefault
           The remote to push to by default. Overrides branch.<name>.remote for all branches, and is
           overridden by branch.<name>.pushremote for specific branches.

       remote.<name>.url
           The URL of a remote repository. See git-fetch(1) or git-push(1).

       remote.<name>.pushurl
           The push URL of a remote repository. See git-push(1).

       remote.<name>.proxy
           For remotes that require curl (http, https and ftp), the URL to the proxy to use for that remote.
           Set to the empty string to disable proxying for that remote.

       remote.<name>.fetch
           The default set of "refspec" for git-fetch(1). See git-fetch(1).

       remote.<name>.push
           The default set of "refspec" for git-push(1). See git-push(1).

       remote.<name>.mirror
           If true, pushing to this remote will automatically behave as if the --mirror option was given on
           the command line.

       remote.<name>.skipDefaultUpdate
           If true, this remote will be skipped by default when updating using git-fetch(1) or the update
           subcommand of git-remote(1).

       remote.<name>.skipFetchAll
           If true, this remote will be skipped by default when updating using git-fetch(1) or the update
           subcommand of git-remote(1).

       remote.<name>.receivepack
           The default program to execute on the remote side when pushing. See option --receive-pack of git-push(1). gitpush(1).
           push(1).

       remote.<name>.uploadpack
           The default program to execute on the remote side when fetching. See option --upload-pack of git-fetch-pack(1). gitfetch-pack(1).
           fetch-pack(1).

       remote.<name>.tagopt
           Setting this value to --no-tags disables automatic tag following when fetching from remote
           <name>. Setting it to --tags will fetch every tag from remote <name>, even if they are not
           reachable from remote branch heads. Passing these flags directly to git-fetch(1) can override
           this setting. See options --tags and --no-tags of git-fetch(1).

       remote.<name>.vcs
           Setting this to a value <vcs> will cause Git to interact with the remote with the
           git-remote-<vcs> helper.

       remotes.<group>
           The list of remotes which are fetched by "git remote update <group>". See git-remote(1).

       repack.usedeltabaseoffset
           By default, git-repack(1) creates packs that use delta-base offset. If you need to share your
           repository with Git older than version 1.4.4, either directly or via a dumb protocol such as
           http, then you need to set this option to "false" and repack. Access from old Git versions over
           the native protocol are unaffected by this option.

       rerere.autoupdate
           When set to true, git-rerere updates the index with the resulting contents after it cleanly
           resolves conflicts using previously recorded resolution. Defaults to false.

       rerere.enabled
           Activate recording of resolved conflicts, so that identical conflict hunks can be resolved
           automatically, should they be encountered again. By default, git-rerere(1) is enabled if there is
           an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was previously used in the repository.

       sendemail.identity
           A configuration identity. When given, causes values in the sendemail.<identity> subsection to
           take precedence over values in the sendemail section. The default identity is the value of
           sendemail.identity.

       sendemail.smtpencryption
           See git-send-email(1) for description. Note that this setting is not subject to the identity
           mechanism.

       sendemail.smtpssl
           Deprecated alias for sendemail.smtpencryption = ssl.

       sendemail.<identity>.*
           Identity-specific versions of the sendemail.*  parameters found below, taking precedence over
           those when the this identity is selected, through command-line or sendemail.identity.

       sendemail.aliasesfile, sendemail.aliasfiletype, sendemail.annotate, sendemail.bcc, sendemail.cc,
       sendemail.cccmd, sendemail.chainreplyto, sendemail.confirm, sendemail.envelopesender, sendemail.from,
       sendemail.multiedit, sendemail.signedoffbycc, sendemail.smtppass, sendemail.suppresscc,
       sendemail.suppressfrom, sendemail.to, sendemail.smtpdomain, sendemail.smtpserver,
       sendemail.smtpserverport, sendemail.smtpserveroption, sendemail.smtpuser, sendemail.thread,
       sendemail.validate
           See git-send-email(1) for description.

       sendemail.signedoffcc
           Deprecated alias for sendemail.signedoffbycc.

       showbranch.default
           The default set of branches for git-show-branch(1). See git-show-branch(1).

       status.relativePaths
           By default, git-status(1) shows paths relative to the current directory. Setting this variable to
           false shows paths relative to the repository root (this was the default for Git prior to v1.5.4).

       status.showUntrackedFiles
           By default, git-status(1) and git-commit(1) show files which are not currently tracked by Git.
           Directories which contain only untracked files, are shown with the directory name only. Showing
           untracked files means that Git needs to lstat() all all the files in the whole repository, which
           might be slow on some systems. So, this variable controls how the commands displays the untracked
           files. Possible values are:

               no - Show no untracked files.

               normal - Show untracked files and directories.

               all - Show also individual files in untracked directories.

           If this variable is not specified, it defaults to normal. This variable can be overridden with
           the -u|--untracked-files option of git-status(1) and git-commit(1).

       status.submodulesummary
           Defaults to false. If this is set to a non zero number or true (identical to -1 or an unlimited
           number), the submodule summary will be enabled and a summary of commits for modified submodules
           will be shown (see --summary-limit option of git-submodule(1)).

       submodule.<name>.path, submodule.<name>.url, submodule.<name>.update
           The path within this project, URL, and the updating strategy for a submodule. These variables are
           initially populated by git submodule init; edit them to override the URL and other values found
           in the .gitmodules file. See git-submodule(1) and gitmodules(5) for details.

       submodule.<name>.branch
           The remote branch name for a submodule, used by git submodule update --remote. Set this option to
           override the value found in the .gitmodules file. See git-submodule(1) and gitmodules(5) for
           details.

       submodule.<name>.fetchRecurseSubmodules
           This option can be used to control recursive fetching of this submodule. It can be overridden by
           using the --[no-]recurse-submodules command line option to "git fetch" and "git pull". This
           setting will override that from in the gitmodules(5) file.

       submodule.<name>.ignore
           Defines under what circumstances "git status" and the diff family show a submodule as modified.
           When set to "all", it will never be considered modified, "dirty" will ignore all changes to the
           submodules work tree and takes only differences between the HEAD of the submodule and the commit
           recorded in the superproject into account. "untracked" will additionally let submodules with
           modified tracked files in their work tree show up. Using "none" (the default when this option is
           not set) also shows submodules that have untracked files in their work tree as changed. This
           setting overrides any setting made in .gitmodules for this submodule, both settings can be
           overridden on the command line by using the "--ignore-submodules" option.

       tar.umask
           This variable can be used to restrict the permission bits of tar archive entries. The default is
           0002, which turns off the world write bit. The special value "user" indicates that the archiving
           user's umask will be used instead. See umask(2) and git-archive(1).

       transfer.fsckObjects
           When fetch.fsckObjects or receive.fsckObjects are not set, the value of this variable is used
           instead. Defaults to false.

       transfer.hiderefs
           This variable can be used to set both receive.hiderefs and uploadpack.hiderefs at the same time
           to the same values. See entries for these other variables.

       transfer.unpackLimit
           When fetch.unpackLimit or receive.unpackLimit are not set, the value of this variable is used
           instead. The default value is 100.

       uploadpack.hiderefs
           String(s) upload-pack uses to decide which refs to omit from its initial advertisement. Use more
           than one definitions to specify multiple prefix strings. A ref that are under the hierarchies
           listed on the value of this variable is excluded, and is hidden from git ls-remote, git fetch,
           etc. An attempt to fetch a hidden ref by git fetch will fail. See also
           uploadpack.allowtipsha1inwant.

       uploadpack.allowtipsha1inwant
           When uploadpack.hiderefs is in effect, allow upload-pack to accept a fetch request that asks for
           an object at the tip of a hidden ref (by default, such a request is rejected). see also
           uploadpack.hiderefs.

       url.<base>.insteadOf
           Any URL that starts with this value will be rewritten to start, instead, with <base>. In cases
           where some site serves a large number of repositories, and serves them with multiple access
           methods, and some users need to use different access methods, this feature allows people to
           specify any of the equivalent URLs and have Git automatically rewrite the URL to the best
           alternative for the particular user, even for a never-before-seen repository on the site. When
           more than one insteadOf strings match a given URL, the longest match is used.

       url.<base>.pushInsteadOf
           Any URL that starts with this value will not be pushed to; instead, it will be rewritten to start
           with <base>, and the resulting URL will be pushed to. In cases where some site serves a large
           number of repositories, and serves them with multiple access methods, some of which do not allow
           push, this feature allows people to specify a pull-only URL and have Git automatically use an
           appropriate URL to push, even for a never-before-seen repository on the site. When more than one
           pushInsteadOf strings match a given URL, the longest match is used. If a remote has an explicit
           pushurl, Git will ignore this setting for that remote.

       user.email
           Your email address to be recorded in any newly created commits. Can be overridden by the
           GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, and EMAIL environment variables. See git-commit-tree(1).

       user.name
           Your full name to be recorded in any newly created commits. Can be overridden by the
           GIT_AUTHOR_NAME and GIT_COMMITTER_NAME environment variables. See git-commit-tree(1).

       user.signingkey
           If git-tag(1) is not selecting the key you want it to automatically when creating a signed tag,
           you can override the default selection with this variable. This option is passed unchanged to
           gpg's --local-user parameter, so you may specify a key using any method that gpg supports.

       web.browser
           Specify a web browser that may be used by some commands. Currently only git-instaweb(1) and git-help(1) githelp(1)
           help(1) may use it.
