DESCRIPTION

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 make®les and shell procedures to improve portability of applications (see make(1)).

EXAMPLES

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

#System is Series 700

Series 700 code fragment goes here

else

# System is Series 800

Series 800 code fragment goes here

WARNINGS

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 sys- tems. Decisions should be based on the hardware and software con®guration information returned by getconf(1).
