NAME
     intro - introduction to maintenance commands and application
     programs

DESCRIPTION
     This section describes, in alphabetical order, commands that
     are  used  chiefly for system maintenance and administration
     purposes.  The commands in this section should be used along
     with  those  listed  in  Section  1  of the User's Reference
     Manual and Sections 1, 2, 3, 4, and 5  of  the  Programmer's
     Reference Manual.  References of the form name(1), (2), (3),
     (4) and (5) refer to entries in the above  manuals.   Refer-
     ences  of  the  form  name(1M),  name(7) or name(8) refer to
     entries in this manual.

     Because of command restructuring for the Virtual File System
     architecture, there are several instances of multiple manual
     pages with the same  name.   For  example,  there  are  four
     manual  pages called mount(1M).  In each such case the first
     of the multiple pages describes the syntax  and  options  of
     the  generic  command,  that is, those options applicable to
     all FSTypes  (file  system  types).   The  succeeding  pages
     describe the functionality of the FSType-specific modules of
     the command.  These pages all display the name of the FSType
     to which they pertain centered and in parentheses at the top
     of the page.  Note that the administrator should not attempt
     to  call  these  modules directly.  The generic command pro-
     vides a common interface to all of them.  Thus  the  FSType-
     specific  manual  pages  should  not be viewed as describing
     distinct commands, but rather as detailing those aspects  of
     a command that are specific to a particular FSType.

COMMAND SYNTAX
     Unless otherwise noted, commands described in  this  section
     accept  options and other arguments according to the follow-
     ing syntax:

     name [option(s)] [cmdarg(s)]
     where:

     name         The name of an executable file.

     option       - noargletter(s) or,
                  - argletter<>optarg
                  where <> is optional white space.

     noargletter  A single letter representing an option  without
                  an argument.

     argletter    A single letter representing an option  requir-
                  ing an argument.




                                                                1

     optarg       Argument (character string) satisfying  preced-
                  ing argletter.

     cmdarg       Path  name  (or  other  command  argument)  not
                  beginning with - or, - by itself indicating the
                  standard input.

     getopt(3C) in the Programmer's Reference Manual.

DIAGNOSTICS
     Upon termination, each command returns 0 for normal termina-
     tion  and  non-zero  to  indicate troubles such as erroneous
     parameters, bad or inaccessible data, or other inability  to
     cope  with  the task at hand.  It is called variously ``exit
     code,''  ``exit  status,''  or  ``return  code,''   and   is
     described only where special conventions are involved.

NOTES
     Unfortunately, not all commands adhere to the standard  syn-
     tax.
