NAME

       Intro, 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.

       Because	of command restructuring for the Virtual File System architecture, there are several instances of multiple manual pages that begin
       with the same name. For example, the   mount, pages - mount(1M), mount_cachefs(1M), mount_hsfs(1M),  mount_nfs(1M),   mount_tmpfs(1M),  and
       mount_ufs(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 list the command followed by an underscore ( _ ) and the FSType to which they pertain. Note that the administrator
       should not attempt to call these modules directly. The generic command provides 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 following 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 requiring an argument.

       optarg	      Argument (character string) satisfying preceding argletter.

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

DIAGNOSTICS

       Upon termination, each command returns 0 for normal termination 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 syntax.
