Well, I was going to be silent, but since you spelled my name funny
(didn't someone else do this last time? :-)...

Sed is fine for this task, but just for a comparison, if you want the
second load average on the line with "marvin", it'd be something like:

set load=`ruptime | perl -ne 'print "$1\n" if /^marvin\s.*,\s*(.*),.*/;'`

I'm presuming that the definition of the desired field is something
like "the sequence of characters between the next-to-last comma and
the last comma, discarding leading whitespace (if any)".  That's what
that regex finds.  (As you parse it, remember that .* matches as
_many_ characters as possible.)

There's your one minute Perl lesson for today, kids.

Just another Perl hacker,
