INTRO(C)                 XENIX System V                  INTRO(C)



     Name
          intro - Introduces XENIX commands.

     Description
          This section describes use of the individual commands
          available in the XENIX Operating System.  Each individual
          command is labeled with either a C, a CP, or a CT for easy
          reference from other volumes.  The letter ``C'' stands for
          ``command''.  The letters ``P'' and ``T'' stand for commands
          that come with the optional XENIX Development System
          (Programming) and the XENIX Text Processing System,
          respectively.  For example, the reference date(C) indicates
          a reference to a discussion of the date command in the C
          section; the  reference cc(CP) indicates a reference to a
          discussion of the cc command in the XENIX Development
          System; and the reference spell(CT) indicates a reference to
          a discussion of the spell command in the XENIX Text
          Processing System.  The Text Processing and Development
          Systems are optional supplemental packages to the standard
          Operating System.

          The ``M'' Miscellaneous section contains miscellaneous
          information including a great deal of system maintenance
          information.  Other reference sections include the ``S''
          System Services section, the ``DOS'' Routines section and
          the ``F'' File Format section.

     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         Is the name of an executable file.

          option       - noargletter(s) or,
                       - argletter<>optarg
                       where <> is optional whitespace.

          noargletter  Is a single letter representing an option
                       without an argument.

          argletter    Is a single letter representing an option
                       requiring an argument.

          optarg       Is an argument (character string) satisfying
                       preceding argletter.

          cmdarg       Is a pathname (or other command argument) not
                       beginning with -. - by itself indicates the
                       standard input.

     Diagnostics
          Upon termination, each command returns 2 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(S) and exit(S)).  The
          former byte is 0 for normal termination; the latter is
          customarily 0 for successful execution and nonzero to
          indicate troubles such as erroneous parameters, bad or
          inaccessible data.  It is called variously ``exit code'',
          ``exit status'', or ``return code'', and is described only
          where special conventions are involved.

     Notes
          Not all commands adhere to the syntax described here.
