Shell Programming and Scripting

Hi,

when i grep for the process "XYZ" , there will be some good number of processes with that name, i want to kill all the these processes at a time using shell script?

Any help needed for this action.

Thanks

killall -r ?

Code:

ps -ef |grep "XYZ"|xargs kill

/usr/bin/kill[8]: root: Arguments must be %job or process ids
getting the above error with command ps -ef |grep "XYZ"|xargs kill

Code:

ps -ef | awk '/XYZ/{print $2}' | xargs kill

killall -e should do it for you without having to invoke grep if you already know the process name.

It also has regular expression support via the -r switch so you should be able to take your grep expression and place it there if you still need to do a regex.

I can't post links yet because I don't have 5 posts, here's an exploded version of the link

linux dot die dot net forwardslash man forwardslash 1 forwardslash killall

[edit] Didn't see the killall -r up a couple posts, leaving here since it has the link for more info

WARNING, WARNING.

If you try killall on a non-Linux system you might be very surprised It often has a more, well, literal meaning.
