In the 6th episode, Shell Scripts, the solution to doesn't provide an explanation on why it works. I think the ending of the script (tail -n 2 | head -n 1) might be confusing to some so it might be nice to explain that we use that set of commands instead of just tail -n 1. Some people may forget that wc shows a total at the end.

Yes, this could benefit from a breakdown of the solution. I usually find asking learners to run the first command, then build up the pipeline by adding add one pipe at a time helps to clarify what is happening.
