Re: Creating PID file

Hi,

Search on search.cpan.org for File::PID and download and install that 
module.

It might help you to create PID files.

To clarify the need for using a PID file, I think it needs to be used for 
example when somebody wants to run a program manually or from a chron job 
but when the admin doesn't want to run the program twice, so he should 
verify if that program is running.
The program runs, opens the PID file, gets the PID from there and verifies

if there is a program with that PID which is running in that moment.
The program can't verify in another way if it is running, because the same

program may be ran with different command lines or links to it.

Am I wrong?
