[wlug] How to figure out what script is starting a process

Hello, I have got compiz fusion to work on my KDE Kubuntu laptop. Compiz is little buggy on KDE so it would be nice to manually start it rather than it automagically start when I login. However, I can't figure out where its getting started from. Is there a way to track what script started a feature. I can find the script for compiz.real but I can't figure out what calls this script. Similary what is the grep command to search a set of configuration files for a key word? I remember someone mentioning it for search kernel sources a few months back. Cheers Chris
