 DESCRIPTION    [Toc]    [Back]
      The following commands return a true value (exit code 0) if the a
      processor type matches the command name.  Otherwise a false value
      (exit code non-zero) is returned.  These commands are commonly used
      within make makefiles and shell procedures to improve portability of
      applications (see make(1)).

 EXAMPLES    [Toc]    [Back]
      Given a shell script that must behave differently when run on an HP
      9000 Series 700 or 800 system, select the correct code segment to be
      executed:

           if hp9000s800
           then
               # system is Series 700 or 800.
                   if hp9000s700
                   then

 WARNINGS    [Toc]    [Back]
      hp9000s800 always returns true on both Series 800 and Series 700
      systems.  Therefore, when using this command in scripts to determine
      hardware type, always use both hp9000s800 and hp9000s700 in the
      appropriate sequence to ensure correct results (see EXAMPLES).

      machid(1) will no longer provide support for future machines beyond
      the Series 800 and Series 700 systems. Decisions should be based on
      the hardware and software configuration information returned by
      getconf(1).
