Re: Killing a process created using system

If you have the process running in parallel (such as with fork, or a piped open), you should be able to send a kill signal to it from your Perl process. But system() doesn't run in parallel; it suspends the parent process.

Hi,
But for this you need to know the process id.
The system command doesn't returns, I think ?

maybe you want to look at
perldoc -f kill
perldoc -f getppid
as a starter to get you going
