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.

HISTORY
     The intro section manual page appeared in 4.2BSD.
