Online liner commit running container, then squashed image
  docker save $(docker commit supatest supatest) | docker-squash -t supatest -verbose | docker load

  docker stop $(docker ps -a -q)
  docker rm $(docker ps -a -q)

  sudo  docker ps -a | grep 'Exited' | awk '{print $1}' | xargs --no-run-if-empty sudo docker rm
