You would be better off to have the script that runs the rsync itself do it. Look at ssh to do this securely: rsync and log the output. Then if whatever file you are interested in changes, you can detect it in the log. ssh can then kick off whatever process remotely you need. -- \ \/ / _ |~\ _ In God We Trust.
