We sometimes need to find a process and kill it regularly, so why not automate it? well its not exactly straight forward when you automate things. you don’t want to accidentally kill random processes etc. so here’s a nice clean way to find and kill a process a couple of different ways.

First if you have a process id via a pid file (the way lane)

kill $(cat /path/to/PID-file)

now if you don’t have that you can still get it and do this via the process name

kill $(ps aux | grep '[p]rocess name' | awk '{print $2}')

or

kill $(ps aux | awk '/[p]rocess/ {print $2}')

PS the reason for the [] around the first char is so the look up command itself doesn’t show in the list.
