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. References 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 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 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 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

SEE ALSO

getopt(1) in the User's Reference Manual.
getopt(3C) in the Programmer's Reference Manual.

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.
