Bearing this in mind you're getting exactly what I'd expect. "-f /tmp/ids maillog.0.bz2" is telling grep to get it's patterns from the file (good luck with that), and as there's no remainder of the line it's being asked to read the data to search from stdin (the terminal at this stage). Probably not what you wanted. I could be wrong about what -f does, but my understanding is that the next argument is the file to read the patterns from. Regards, Frank.
