Killing multiple processes

Kyle D. Harris — Thu, 17 Jul 2003 19:00:50 GMT

I have a script that loops which sends out constant processes called "filesystem alert" which is the name of my script. How do i go about killing all processes running that are named filesystem alert? This is pretty urgent, thanks to anybody that can help!!!

The attached script might help. It is quite powerful, use it wisely.

ps -ef | grep filesystem| awk '{print $2}' > pids

then vi the file pids to put kill -9
(or whatever) at the begining of every line

:%s/^/kill -9 /

make it exacutable

chmod 775 pids

then run it

./pids

Then don't run that script again :)

Hi Kyle,

The safest, but not easiest or fastest way, is to determine all the PIDS by

ps -ef | grep -i "filesystem alert"

Then

kill PID(s)

So let's say that PIDs 1065 6544 8732 1208 are all "filesystem alert" PIDs.

kill 1065 6544 8732 1208

I don't like to do "mass" kills via a script or one-liner unless I'm 100% sure the PIDs will all & always be correct. You kill the wrong PID & you can really mess up a system.

Rgds,
Jeff

Hi Kyle:

SWIth rgard to the 'kill' avoid using a 'kill -9' if at all possible! Use it only as a last resort. 'kil -9' cang't be caught and thus gives a process no chance to cleanup files and remove shared memory segments.

Start with a simple 'kill'. If that doesn't work, try again with 'kill -hup'. As a last resort (only) issue 'kill -9'.

Regards!

Hello!

Try this:
ps -ef | grep "filesystem alert" | awk '{print $2}' | xargs kill
