no. consider the differing output from the following invocations:
$ ps aux
$ ps --version
$ ps aux --version
it may be that the result of doing something like
# service httpd status --version
was deliberately designed that way, but it's certainly less than
intuitive.
in any event, the only point i was making was that, in using
/sbin/service as a sample script to show some people how scripts work,
even those people who had never seen a script before took a look at
the logic of that utility and were thinking, "what the hell ..."
