Interactive perl based application who works as per schedule

[Benjamin Fernandis]

Hi,


I develop some scripts which we use with OS crontab to schedule to run
certain scripts. Scripts are for backup , VM on/off etc...

I want to integrate crontab function within perl script to do this.

Like a perl based daemon, which accepts date/time and action from users and
run according to that.

currently i define in cronjob

example : 10 10 * * * /opt/scripts/stop_vm.pl <VM_ID>


What is the better way to make it interactive with other team members , so
they can add/modify/remove schedule jobs with scripts.

I am thinking to make it as web based and different scripts which we are
currently using ( stop_vm.pl , start_vm.pl , backup.pl etc...), convert
them into module and then use those modules from main script which acts as
per schedule and complete certain task.

Please suggest me for this.

Regards

I suggest you don't try to re-invent cron. Cron works. Cron is a known
quantity. You don't need to re-invent cron.

What you need is a way to let other people edit crontab files, with a
better UI. So make a Perl web application. Require authentication --
tie it into your AD or LDAP or whatever -- and provide a UI that
writes out a crontab file based on the users input.

Then have a cronjob that runs every minute that looks at those crontab
files, detects when one has been changed, and reloads it.

chrs,

Hi!

I just read a article on perltricks.com about every. It's an application
written in Perl,which provides a interface to cron.

Maybe you want to use it in your (web-)application.
