Quick one liner to purge docker containers and images

Does what it says on the tin. I'm using fish so my one liner looks like this:

docker rm (docker ps -a -q) && docker rmi -f (docker image ls -q)

If you're running a more standard shell like bash, you'll probably need some $s in there:

docker rm $(docker ps -a -q) && docker rmi -f $(docker image ls -q)

It's pretty simple - docker rm removes containers. It accepts a list of container Ids. docker ps -a -q lists all containers in quiet mode - so just the container Ids.

The logic is the same for removing images - I've thrown in the f force flag for good measure, and I've used && to concatenate two commands onto one line.

This will error out if you have no containers. Be warned.
