21.2 'arch': Print machine hardware name
========================================
'arch' prints the machine hardware name, and is equivalent to 'uname
-m'. Synopsis:
arch [OPTION]
The program accepts the *note Common options:: only.
'arch' is not installed by default, so portable scripts should not
rely on its existence.
An exit status of zero indicates success, and a nonzero value
indicates failure.
