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.
