How to find that some perl program is already running.

[shrek123]

Hi,

I have to call a perl program(if it is not running) from a perl program
How can I check if my program is already running or not.

I somehow, didn't like the idea of using some file as tag.

My platform could be a MAC OS or windows.

Please throw some light on how can I do it.

Thanks and Regards,
Shrek

Maybe you can get a list of running programs from the operating system and parse the output to see if the perl programs name is in there. I have no Mac experience but with Windows it most likely depends on which version you are using.
