can't stop a process using pkill

2007fld · 09-10-2007, 10:56 AM

I have a process running constanly:

Quote:

ps -ef | grep username1
username1 17704 1 0 08:29:34 pts/5 0:00 /usr/bin/perl /u00/usr/bin/load_balancer/perl_responder.pl

I can find the process using pgrep:

Quote:

bash-2.05$ pgrep -l perl_responder
17704 perl_responder.

But I can NOT stop the process using pkill:

Quote:

bash-2.05$ pkill -x perl_responder
bash-2.05$

And the prcess is still running.

Please help!! Thanks!

Maybe it has a parent process you need to kill?

How about trying the kill command and the process ID?

Code:

kill -9 17704

PID varies every time when the perl scripts gets executed.

I used pkill -f perl_responder, and it works.

That's the way to do it. (Using the full argument list in the process table.)

For future reference, you can troubleshoot this using pgrep to make sure it's matching a PID.

edit: I need to learn to read early in the morning. To elaborate on that, use -f with pgrep as well.
