[LAU] getting cpu usage on commandline

Hi

I'm doing some benchmarking and would like to know the cpu usage of
certain realtime processes. ATM I use htop, but I'd like to make an
automatic test script, and it seems htop cannot be made to output to
stdout and exit. Also "ps aux" seems to be reports wrong cpu usages for
realtime processes.

Which command can I call (from a bash script) to get the actual cpu
usage of a realtime process?
