In fact, as I recall the shell will parse the result of `cat IP_text` into arguments, so I'm surprised that doesn't give you an ocean of file not found errors. Try grep --file='IP_text' /var/log/messages Keep in mind that a period (.) matches any character except newline, so you may end up with a few IPs that weren't in the list. -- Brian - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
