just joined the forum. and this thread is very old as well.

but would like to make a comment if some searcher can get this helpful.

you can schedule your script in cron to run every minute
and in your perl script check at the starting if another instance of script is running.
if so ...quit. else continue..


dont tell me that you need a code as well for this.. its pretty simple and wont take more then 3 lines..
