I do not know about the busybox question but in general to search whether a process, say cdrdao, is present I would use a regexp that matches the cdrdao command line but _not_ the grep command line itself: <$> ps auwwwwwwwwwwww|grep cdrdao myuser 15160 0.0 0.4 1748 520 pts/27 R+ 16:56 0:00 grep cdrdao <$> ps auwwwwwwwwwwww|grep [c]drdao On the contrary, your regexp match itself, like the first of my two examples above ... -- Chi usa software non libero avvelena anche te.
