The file will never be deleted ?? It's a nasty hack, but you chould run a separate shell script to check for the existance of the running script, then call the script if it's not running. something like (/bin/sh): PID=ps aux | grep [program] | grep -v grep | awk {'print $2'} Replace [program] with the program name. That'll get you the PID if the script is already running. You can kill it, or just exit instead, for example. That's one way.. -- Brian Clark | Avoiding the general public since 1805!
