I need to kill a few Python processes. I can get a list of the process numbers using pgrep python, but how can I kill them all at once instead of killing one by one?
I'm looking for something like:
pgrep python | kill process_nos

You can try:
pgrep python | xargs kill

1No, "kill $(pgrep name)" is still two processes and a shell. For one process, use
pkill(as pointed out by @tink: superuser.com/a/742741)– vogApr 24, 2018 at 7:41
pkill python
Short and sweet, man pkill for details.

I found that
pkill pythondoes not always work, in cases wherekill PIDneither works. Butpgrep python | xargs kill -9does. Can pkill do the equivalent?– JeppeNov 17, 2019 at 12:29 -

1Bare in mind that it the process is stuck on e.g. broken I/O that, too, may not work. But in those cases only a reboot will ...– tinkNov 17, 2019 at 16:45
@tink has the correct answer, but I wanted to add that you want to make sure you are using the correct format for your machine. If you are using a Linux machine, pkill python is correct, but if you are using a Mac terminal, you will want to use pkill Python. So the most correct answer would be this:
pkill <process_name>
where <process_name> is the case-sensitive name of the process to kill.
Note: I understand that the tags for this question were related to Ubuntu Linux, but I wanted to clarify this for anyone that has a different machine but had this exact question (like myself).
If pkill is a bit too radical for your tastes and you prefer to select which entries of the pgrep listing you want to kill, you can have a look at ezkill <https://github.com/Kraymer/ezkill> that i wrote.
Simply just run -
sudo kill -9 `pgrep python`
man killall...
