Bart and I took a few minutes upfront to high-five each other for 150 episodes of the Programming By Stealth Podcast. Then we quickly got to work.

Back in the Taming the Terminal podcast (at [ttt.bartificer.net/…](https://ttt.bartificer.net/), Bart taught us about stream redirection, or what he likes to call Terminal Plumbing. This was a long time ago and many folks may not have listened to that great series. Bart takes us through it again but from the perspective of writing Bash scripts that can do everything we can do in the Terminal. We learn about Standard Input (STDIN), Standard Output (STDOUT), and Standard Error (STDERR). We also learn how to bifurcate STDOUT and STDERR to produce desired results. He walks us through how to use the symbols `>`, `<`, and our friend the pipe `|` to redirect output from commands and files. I did get stuck for quite a while in a few spots here and there. Bart continues to try to convince me that if I’m confused, at least one other learner is as well, so hopefully making Bart find different ways to explain these things to help me will help you.
