Docker stuff

Removing all docker containers in one go

docker container rm `docker ps -a | cut -f 1 -d " " | tr "\n" " "`

We are using command line substitution with the ``, and populating the container ids inside it. The cut gets the first field from docker ps, that is the id, and the tr replaces the newline with a space, so that we get all ids in a single line.

Btw, this will also work in the new Linux Subsystem for Windows(LSW) command line, its able to see the docker container created from windows command line.
