stopping a perl script

safra · 07-07-2002, 11:56 AM

Hi,

I am experimenting with a perl script run from the command prompt and looping in the background.

This is working fine. But as I am tweaking the perl script I need to be able to restart it.

When I try this I get the message:
Address already in use

How can I stop the script that is currently running in order to test the new one?

Thanks,
Ron

ps -ef
will give you all the processes currnetly running on your system with their PID's, just grep the script from it
ps -ef | grep -i script_name | grep -vv grep
use
kill -9 process id (PID)
to kill it
P.S. if the script is just used to run a job at background something like
system ("mozilla &");
then you should grep out the background process in this case mozilla and kill it.

killall perl_script_name

Before diving into Perl you should learn the basic of Unix administration srtarting with this how to:

Another way is to bring the command back to the foreground and [Cntrl]+c

ie.

$ my_scipt.pl &

$ fg

$ my_script.pl; [Cntrl]+c

You guys are quick!

I just found out about kill. But then I thought how to get the matching process process number so thanks for that tip NEO77777

Thanks for those links and especially that last tip, Pickledbeans. Makes things easier!
