Find and Kill All Processes

Posted on Edited on

When I found CPU usage is higher than usual, I used to do two things:

  1. Use ps & grep to filter possible processes
1
ps aux | grep ruby
  1. Kill the processes
1
kill PROCESS_ID

However, if there are lots of processes to kill, it would be great if you merge these two steps and one more powerful tool awk:

1
kill $(ps aux | grep 'guard' | awk '{print $2}')

Nice and easy.
