#bash# grep '[c]ron' cron cron grep cron grep cron So the 'grep cron' is matched by the above command. So as per regular expression grep '[c]ron' and grep 'cron' are same. Oh and i got it that ps ax | grep '[c]ron' will search for 'cron' in the ps output and thus the grep always used to show only 'cron' when ps ax | grep '[c]ron' is executed. Only the ps output differs based on your command and thus it does not match. I think this is wat you meant but i could get it only after some thinking! ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
