As a builder, I would like the ability to create a course teaching bash shortcuts.

Some bash features are not just about typing something in to get the correct output. I would like the ability to create a course that teaches the user to use bash shortcuts to efficiently use bash. It would be nice if they could see the effects of the shortcut real time, and simultaneously receive feedback on whether they did the correct thing.

The issue names no files, tests, or entry points, so first inspect the Python CLI structure and how existing courses are represented. Define the course scope around Bash shortcuts, real-time visible effects, and correctness feedback; done means users can complete the course and receive both kinds of feedback.
