in reply to running perl file

There sure is: Set up the perl script as a service process so that it runs continuously, and add an event handler for timer events. You can integrate it into systemd (or Windows services) so that it starts automatically after booting and re-starts after an error. You can, if you want, re-implement all parts of cron you consider interesting!
