   9 DESCRIPTION
  10        This section describes, in alphabetical order, commands that are used
  11        chiefly for system maintenance and administration purposes.
  12 
  13 
  14        Because of command restructuring for the Virtual File System
  15        architecture, there are several instances of multiple manual pages that
  16        begin with the same name. For example, the   mount, pages  mount(1M),
  17        mount_hsfs(1M), mount_nfs(1M), mount_tmpfs(1M), and mount_ufs(1M). In
  18        each such case the first of the multiple pages describes the syntax and
  19        options of the generic command, that is, those options applicable to
  20        all FSTypes (file system types). The succeeding pages describe the
  21        functionality of the FSType-specific modules of the command.  These
  22        pages list the command followed by an underscore ( _ ) and the FSType
  23        to which they pertain. Note that the administrator should not attempt
  24        to call these modules directly. The generic command provides a common
  25        interface to all of them. Thus the FSType-specific manual pages should
  26        not be viewed as describing distinct commands, but rather as detailing
  27        those aspects of a command that are specific to a particular FSType.

  29 COMMAND SYNTAX
  30        Unless otherwise noted, commands described in this section accept
  31        options and other arguments according to the following syntax:
  32 
  33          name [option(s)] [cmdarg(s)]
  34 
  35 
  36 
  37        where:
  38 
  39        name
  40                       The name of an executable file.
  41 
  42 
  43        option
  44                       noargletter(s) or,
  45 
  46                       argletter<>optarg
  47 
  48                       where <> is optional white space.
  49 
  50 
  51        noargletter
  52                       A single letter representing an option without an
  53                       argument.
  54 
  55 
  56        argletter
  57                       A single letter representing an option requiring an
  58                       argument.
  59 
  60 
  61        optarg
  62                       Argument (character string) satisfying preceding
  63                       argletter.
  64 
  65 
  66        cmdarg
  67                       Pathname (or other command argument) not beginning with
  68                       or, by itself indicating the standard input.

 108 DIAGNOSTICS
 109        Upon termination, each command returns 0 for normal termination and
 110        non-zero to indicate troubles such as erroneous parameters, bad or
 111        inaccessible data, or other inability to cope with the task at hand. It
 112        is called variously ``exit code,'' ``exit status,'' or ``return code,''
 113        and is described only where special conventions are involved.
 114 
 115 NOTES
 116        Unfortunately, not all commands adhere to the standard syntax.
