I want to write a Perl code that ends the process of another program of mine, running on Linux.

For example, I execute xxy.py and a process is opened for it. I would like to use Perl to close the process of xxy.py. What do I need to do?

Perl extensions are typically .pl or .pm right? .py is for python I think.

Anyway, you can kill a specified program in a Unix environment with something like:

system 'killall', 'some_program_name';

or

system 'kill', '-15', $pid;

if the variable $pid holds the pid of your program.
