INTRO(1M)INTRO(1M)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 architec‐
ture, 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 argu‐
ment.
argletter
A single letter representing an option requiring an
argument.
optarg
Argument (character string) satisfying preceding arglet‐
ter.
cmdarg
Pathname (or other command argument) not beginning with
− or, − by itself indicating the standard input.

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.
