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

     intro -- introduction to system maintenance procedures and	commands

     This section contains information related to system operation and mainte-

     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.

     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.

     A number of pages in this section describe	general	system management top-

     For example, the boot(8) manual page describes the	system bootstrapping
     procedures, and the diskless(8) manual page describes how to boot a sys-
     tem over a	network.  The crash(8) manual page should be consulted to un-
     derstand how to interpret system crash dumps.

     The intro section manual page appeared in 4.2BSD.
