Preventing a script from running if it's already running

[edimusrex]

I am searching for a simple way to prevent a script from running if it's already running. In python I've used singleton from the tendo package, is there a similar module for Perl? I was looking into Class::Singleton but am not 100% sure if that's what I should be exploring.

Advice would be greatly appreciated

I'm fond of this approach: Sys::RunAlone. This has been discussed here many times. Here's one big old thread and there are others if you search: Ensuring only one copy of a perl script is running at a time

Excellent, I will read up on it.

Thanks

Check out Ensuring only one copy of a perl script is running at a time. There are lots of viable options.
