KILL A LINUX PROCESS BY PROCESS NAME

If you have a situation where you need to find and kill a specific process by name or script name, you can use this command:

kill `ps -ef | grep YourProcessName | awk ‘{print $2}’`

This is invaluable in cases where the same process command (python, java, etc.) is being used for multiple scripts. For example, there are a few different python processes running on my webserver, but I only want to kill one of them. So, instead of using:

kill $(pidof python)

which kills the first python process, or:

killall -9 python

which kills ALL running python processes, I can just specify the process by the actual python script that is running.
