Schedule::Cron - cron-like scheduler for Perl subroutines
This module provides a simple but complete cron like scheduler. I.e this modules can be used for periodically executing Perl subroutines. The dates and parameters for the subroutines to be called are specified with a format known as crontab entry see manpage crontab5 or documentation of ScheduleCron.
The philosophy behind ScheduleCron is to call subroutines periodically from within one single Perl program instead of letting cron trigger several possibly different Perl scripts. Everything under one roof. Furthermore ScheduleCron provides mechanism to create crontab entries dynamically, which isn’t that easy with cron.
ScheduleCron knows about all extensions well, at least all extensions I’m aware of, i.e those of the so called “Vixie” cron for crontab entries like ranges including ‘steps’, specification of month and days of the week by name or coexistence of lists and ranges in the same field. And even a bit more like lists and ranges with symbolic names.
