a file used as a lock file? (have the shell script remove the file when it's done) - possibly in combo with flock()? if the lock file exists (or cannot be created because it already exists - depending on how you fancy implmenting it) then don't try to run the script. have the shell script check the process list for itself and return straight away with an error (or some useful message) if it finds its self? - my gut says this is the more robust/nicer method. er .... um ... nope no more ideas here :-) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
