Please reply to the list so that others can see the conversation. Search for cron on Google to learn more about it. You can also type "man cron" and "man crontab" on the command-line. I would suggest writing a simple PHP wrapper script that checks the DB, runs the Perl script if it needs to, and stores the Perl script's output. You could also write the wrapper in Perl or just alter the Perl script. :-)
