How to kill a process by name on Ubuntu

On the previous article i show you how to kill process using kill command, which require process id (PID) of the program that you want to kill. But actually you can also kill a process by it's name.

To kill a process by the name, you can use 'killall' command, instead of 'kill', like this:

sudo killall -9 [process-name]

Example:

sudo killall -9 firefox

sudo killall -9 thunderbird

sudo killall -9 rhythmbox
