schedule custom commands execution

Hello to you all.

I have a whole bunch of custom commands that I executehere and there when need be. I am lazy and I scripted my repetitive tasks.

I have found their location on disk in /etc/webmin/custom/99999.cmd I would like to execute many of them on a cron. I have looked inside the cmd file but it's concatenated with stuff that the shell can't accept.

Is there a way with webmin/virtualmin to execute any/some/all custom commands at an exact time I would see fit?

Thanks in advance for any pointer on the subject.

Best regards.

Marc
