I need the pid for a process given its owner and its command. I can filter a process per user with "ps -u xxx" and its command by "ps -C yyy", but when I try "ps -u xxx -C yyy", they are combined using OR logic. I need AND logic. How can I accomplish this?

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:
du -hs * | sort -h
If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:
brew install coreutils
du -hs * | gsort -h
From sort manual:
-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)

Use pgrep?
it returns just the pid (or pids, if more than one process matches).
