Killing multiple process instances from the terminal

I sometimes have multiple instances of a process running, typically, worker scripts that are dealing with clearing out a backlog. From time to time, I’ll need to kill these scripts for one reason or another and it’s a pain in the swiss to copy and paste the ids of each process and kill individually. Below is the command I use to kill all running instances of myscript.rb.

ps -deaf | grep -v grep | grep myscript.rb | awk '{ print $2 }' | xargs sudo kill -9

Essentially, this just greps through the process list for all processes with the name myscript.rb, cuts out their process ids and pipes them to the kill command. The grep -v grep command simply excludes the grep search from the list of process ids.
