INTRO(8)                  BSD System Manager's Manual                 INTRO(8)

NAME
     intro -- introduction to system maintenance and operation commands

DESCRIPTION
     This section contains information related to system operation and maintenance.  It describes commands
     used to create new file systems, newfs(8), verify the integrity of the file systems, fsck(8), control
     disk usage, edquota(8), maintain system backups, dump(8), and recover files when disks die an untimely
     death, restore(8).

     All commands set an exit status.  Its value may be tested to see if the command completed normally.
     Unless otherwise noted (rare), the value 0 signifies successful completion of the command, while a
     value >0 indicates an error.  Some commands attempt to describe the nature of the failure by using
     error codes defined in sysexits(3), or set the status to arbitrary values >0 (typically 1), but many
     such values are not described in the manual.
