@rachel On a reasonably sized but idle server I have almost 900 processes with 0.0% CPU usage. How do you pick a single process out of that list?

I fear the attempt to "filter out" only the on task with the lowest CPU will yield that very task - e.g. "top -b -n 1 -o %CPU | tail -1" will run top in batch mode, exactly once, sorted by CPU descending and then discards all but the last line. However that last line will probably be the "tail" process itself.
