NAME
       intro - introduction to system maintenance commands and application
       programs

DESCRIPTION
       Section 1M (aman/man1) describes, in alphabetical order, commands
       that are used chiefly for system maintenance and administration.
       Other DG/UX commands appear in Section 1 (pman/man1 and uman/man1).
       See the contents(0) manual page for an alphabetized list of all DG/UX
       commands.

   Command Syntax
       Unless otherwise noted, commands described in this chapter accept
       options and other arguments according to the following syntax:

       name [option(s)] [cmdarg(s)]

       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 two bytes of status, one
       supplied by the system and giving the cause for termination, and (in
       the case of normal termination) one supplied by the program (see
       wait(2) and exit(2)).  The former byte is 0 for normal termination.
       The latter is customarily 0 for successful execution, and non-zero
       for such problems as erroneous parameters, or bad or inaccessible
       data.  It is called variously ``exit code'', ``exit status'', or
       ``return code'', and is described only where special conventions are
       involved.

SEE ALSO
       contents(0), getopt(1), getopt(3C).

NOTE
       Many commands do not adhere to the described syntax.
