How to kill all processes matching a name?

Question

Say I want to kill every process containing the word amarok. I can print out the commands I want to execute. But how do I actually make the shell execute them. ie.

Answer 1

ps aux | grep -ie amarok | awk '{print $2}' | xargs kill -9 

xargs(1): xargs -- construct argument list(s) and execute utility. Helpful when you want to pipe in arguments to something like kill or ls or so on.
