How to kill line of PID?

Question

I have process which created multiple PID's. I want to kill all those PID's. I have tried
pkill <process_name>.

But PID not getting killed as they were wait to resource releasing.

I have managed to get PID list with

ps -ef | grep <process_name> | awk '{print $2}'

which gives process ID list but how can I kill all those listed PIDs ?

Thank you.

what's the output of pgrep -lf <process_name> ? if it gives only the relevant processes, you can kill with pkill -f <process_name> — Dani_l

@l0b0 Why? because some web page says so? The pgrep -lf verification covers everything that page warns about. You can see exactly what you are about to pkill. — Dani_l

@l0b0 how is pgrep/pkill different from ps -ef | grep <prco name>? Since it doesn't, you claim the authoritative answer is - since you didn't think to store the ppid in advance, you're out of luck. Don't trust ps names. They might lie. — Dani_l

Hold on, I didn't say to use pgrep/pkill instead of ps | grep; they're equally bad. If you read the linked web page it explains how to do it cleanly, by making sure that the parent process is responsible for killing/relaunching processes rather than relying on a PID file or pgrep/pkill. Of course, I assume OP is trying to automate this because of the form of the question. If that's not the case there's no point in being picky. — l0b0

You could pipe the output to xargs e.g.

ps -ef | grep <process_name> | awk '{print $2}' | xargs /bin/kill

But why doesn't your pkill command work?

With

pgrep process_name | xargs kill

or

ps -e | awk '/[p]roces_name/ {system("kill "$1}
