Question

I have a multiple processes with a similar keyword. I have to kill all the process at one shot. Like

  ps -ef |grep raj
root      3129     1  0 15:32 ?        00:00:00 /usr/lib/raj/msisdn
root      3165     1  0 15:36 ?        00:00:00 /bin/sh /usr/lib/raj/raj-1.sh
root      3166  3165  0 15:36 ?        00:00:00 /usr/lib/raj/raj-2
root      3170  2236  1 15:36 pts/0    00:00:00 grep raj

I heard that this can be done using awk. One liner command to kill all the process is what I need 🙂

Answer 1

What about:

pgrep -f raj | xargs kill

I’d recommend running

pgrep -f raj | xargs ps

first, to make sure you’re killing the right processes.

EDIT: If you want to use awk, try:

ps -ef | grep raj | awk '{print $2}' | xargs kill

but it’s more verbose than pgrep and kill.
