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/

Some cases you might want to kill all the process running in a specific port. For example, if I am running a node app on 3000 port and I want to kill that and start a new one; then I found this command useful.

Find the process IDs running on TCP port 3000 and kill it

kill -9 `lsof -i TCP:3000 | awk '/LISTEN/{print $2}'`
