SCP(1)                    BSD General Commands Manual                   SCP(1)

NAME
     scp -- secure copy (remote file copy program)

SYNOPSIS
     scp [-12346BCEpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port]
         [-S program] [[user@]host1:]file1 ... [[user@]host2:]file2

DESCRIPTION
     scp copies files between hosts on a network.  It uses ssh(1) for data transfer, and uses the same
     authentication and provides the same security as ssh(1).  Unlike rcp(1), scp will ask for passwords or
     passphrases if they are needed for authentication.

     File names may contain a user and host specification to indicate that the file is to be copied to/from
     that host.  Local file names can be made explicit using absolute or relative pathnames to avoid scp
     treating file names containing `:' as host specifiers.  Copies between two remote hosts are also per-mitted. permitted.
     mitted.

     The options are as follows:

     -1      Forces scp to use protocol 1.

     -2      Forces scp to use protocol 2.

     -3      Copies between two remote hosts are transferred through the local host.  Without this option
             the data is copied directly between the two remote hosts.  Note that this option disables the
             progress meter.

     -4      Forces scp to use IPv4 addresses only.

     -6      Forces scp to use IPv6 addresses only.

     -B      Selects batch mode (prevents asking for passwords or passphrases).

     -C      Compression enable.  Passes the -C flag to ssh(1) to enable compression.

     -E      Preserves extended attributes, resource forks, and ACLs.  Requires both ends to be running Mac
             OS X 10.4 or later.

     -c cipher
             Selects the cipher to use for encrypting the data transfer.  This option is directly passed to
             ssh(1).

     -F ssh_config
             Specifies an alternative per-user configuration file for ssh.  This option is directly passed
             to ssh(1).

     -i identity_file
             Selects the file from which the identity (private key) for public key authentication is read.
             This option is directly passed to ssh(1).

     -l limit
             Limits the used bandwidth, specified in Kbit/s.

     -o ssh_option
             Can be used to pass options to ssh in the format used in ssh_config(5).  This is useful for
             specifying options for which there is no separate scp command-line flag.  For full details of
             the options listed below, and their possible values, see ssh_config(5).

     -P port
             Specifies the port to connect to on the remote host.  Note that this option is written with a
             capital `P', because -p is already reserved for preserving the times and modes of the file in
             rcp(1).

     -p      Preserves modification times, access times, and modes from the original file.

     -q      Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).

     -r      Recursively copy entire directories.  Note that scp follows symbolic links encountered in the
             tree traversal.

     -S program
             Name of program to use for the encrypted connection.  The program must understand ssh(1)
             options.

     -v      Verbose mode.  Causes scp and ssh(1) to print debugging messages about their progress.  This is
             helpful in debugging connection, authentication, and configuration problems.

EXIT STATUS
     The scp utility exits 0 on success, and >0 if an error occurs.
