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

Why would you invoke THREE processes when one suffices? –  tink Apr 17 '14 at 9:23
    
For one process it would be kill $(pgrep name) –  Vadim Kirilchuk Feb 8 at 17:56
pkill python

Short and sweet, man pkill for details.

@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).
