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 crontab(5)
|
|
or documentation of Schedule::Cron).
|
|
|
|
The philosophy behind Schedule::Cron 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 Schedule::Cron provides mechanism to
|
|
create crontab entries dynamically, which isn't that easy with cron.
|
|
|
|
Schedule::Cron 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).
