In this first segment we'll lay a very basic foundation. We plan to take things very slowly with this series, so Bart gives us a sort of 40,000ft view of command shells – some context, some history, a very general description of what command shells do, and a little bit on why they are still very useful in the modern GUI age.

As always, you can get to Bart's fabulous tutorial shownotes at ttt.bartificer.net/...
