From the man page, `u' implies `-r', which means "sort by CPU time". Processes with the exact same CPU time will be sorted by PID, as you were expecting. It used to be that processes with "close to the same CPU time" were treated as being exactly the same (due to round-off error), and thus it used be much more likely to see many processes listed in PID order. It's possible that there's some bug there, but the last time I looked into this it seemed to be doing the right thing. I plan to look into it again, because someone else has reported that there might be a bug in there. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
