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 mainte-
     nance.  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).  Network related services like
     inetd(8) and ftpd(8) are also described.  The crash(8) manual page should
     be consulted to understand how to interpret system crash dumps.

     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 indi-
     cates 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.
