My daughter was advised/encouraged by their teacher to take a Linux (sic) command line course.

She was enjoying it until she unexpectedly hit a paywall at chapter 4 (of 6).

Can you recommend a free as in freedom GNU/Linux command-line course or tutorial?

@janneke I know of Command Challenge, but I thought its a little more advanced that absolute beginner. The source code is on Gitlab (which is suboptimal but better than Github I guess), and is MIT licensed.
