I created a super simple dummy demo Shell for non-technical people so they can get a feeling how working on a commandline feels like without having to install anything or the fear of breaking things. It only has a few commands so far and outputs hard-coded dummy content.
Available commands so far: ls, cp, pwd, less, host, touch, ssh, clear
