you're right this is probably better inside the shell. That'd make it more cross platform too. I was thinking a different approach on how it'd work. Since the goal is teaching, I'd prepopulate it with support for really basic stuff like cat, ls, echo etc. And the bottom portion would be focused on teaching how these commands work and guiding through most common use cases. Then as the user advances, they could install new modules. Maybe they now want to start text processing so could recommend they install the grep, awk or sed modules and then begin taking those tools on.
