INTRO(8) Maintenance Commands and Procedures INTRO(8)
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(8),
mount_hsfs(8),
mount_nfs(8),
mount_tmpfs(8), and
mount_ufs(8). 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)

with

attributes(7)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.
