RE: Question Re: Piping and Redirection

Reading this debate day in and day out has be thinking about writing a damn 
tail program. There's no question that it could be done. Perhaps a first pass 
would be a message queue monitor that updates automatically and dynamically 
adjusts filtering to the user's specifications. Next step, a DB monitor?

When using tail to monitor files (log files or any other file) you can
filter what you want by piping with grep:

tail -f /my/file | grep "string to watch for"
