For some reason, that doesn't work on my system. It's a minor variant on
one of the things I mention in my original post. I just had the -f1
before the -d' '. I tried your version just now, but all I get back is a
blank line. Not sure if I'm getting an empty line or a space on a line,
but it's not the pid.

Interesting. I probably heard that in a class last year, but since I
haven't had a reason to use it have forgotten it. Thanks.
