PBS 148 – A Bash Potpourri (Subshells, Relative Paths & More)

This week’s Programming By Stealth is a great lesson on how no matter how long you’ve been coding, you’ll still get caught out from time to time and think that the universe makes no sense. When Bart was working on the challenge from PBS 147, he ran into a bizarre situation for many hours. He eventually figured out what was going on, but it changed this installment into a walk down what went wrong, what he learned, and gave him the opportunity to teach us even more about shell scripting. The entire installment is all about the solutions to the challenge from PBS 147 so you might want to take a shot at it yourself before listening to or reading this week’s installment. Before we get started, I also explained how we now have a terrific way to share our work on the challenges, through a GitHub Organization called pbs-students. I wrote it up in the article entitled [Introducing the Programming By Stealth Student Organization in GitHub](https://www.podfeet.com/blog/2023/03/pbs-students-github) You can find Bart’s fabulous tutorial shownotes at pbs.bartificer.net.

It’s by invitation only but all you have to do is ask Allison!
