Time Controlled Execution in Virtual Domain (& sub dirs)

[millimeter]

Greetings,

I am a ammeter Perl programmer looking for a method to run a script or some operation (shell.. etc) based on time. I looked into cron but this as I understand is one per server, not virtual domain.

For example I need to execute a script that reads a text file once every hour based on an action taking place to start it until another action takes place.
Start - A particular script is accessed, this signals the start. The nest time the script is accessed it single a stop.

Is this possible with Perl, Shell...?

Thanks for your help.

You should speficy better what do you need to do, because it's not clear.
The cron is generally the better system to execute script periodically, there is no need to write other daemons.

BYe.
