How to kill a process in MacOS?

Question

I tried kill -9 698 but the process did not die.

$ ps -ef | grep chromium
  502   698   811   0   0:01.24 ??         0:07.28 /Users/lucius/chromium/         


        

Answer 1

If you're trying to kill -9 it, you have the correct PID, and nothing happens, then you don't have permissions to kill the process.

Solution:

$ sudo kill -9 PID

---

Okay, sure enough Mac OS/X does give an error message for this case:

$ kill -9 196
-bash: kill: (196) - Operation not permitted

So, if you're not getting an error message, you somehow aren't getting the right PID.
