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

     intro - introduction to system maintenance and operation commands

     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).  The format(8) manual for
     the specific architecture the system is running on should be consulted
     when formatting disks and tapes.  Network related services like inetd(8)
     and ftpd(8) are also described.  The section crash(8) 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
     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.

     The intro section manual page appeared in 4.2BSD.
