There is this itch that tiling window manager users feel. Whether it is caused by surfing the world of r/unix or the want for change, it might be useful to have a way to easily switch between window managers. This article shows how to achieve this using already installed applications on your system.

A BASH on the head.

On most sane Linux distributions, BASH is provided as a default shell script interpreter, I will be using that. When I said minimal, I meant minimal. With barely 38 lines, I know no other contestant. For a bonus, I will also use sx & ssh-agent.
