After our annual break from Programming By Stealth that happens at an unknown time for an unknown length every single year, Bart and I are back with a new episode of Programming By Stealth. Bart introduces us to a language called jq and a terminal command called jq which together are used to help query […]

CCATP #775 — Bart Busschots on PBS 154 — Bash: Expansions & Brackets Redux
Bart Busschots joins us for Programming By Stealth with the final installment of our miniseries on Bash. He explains a few new concepts, but the real value of this installment and especially his fabulous tutorial shownotes is that he compiles a lot of info into some tables for us to use as reference for the […]

In Programming By Stealth, we’ve come to the end of our journey with Bash. I’ll be sad to have it complete because as I tell Bart in this episode, I’ve really enjoyed it. Next time he will do a final bow-tying episode where he brings everything we learned together in one set of notes as […]

In Programming By Stealth 152A Bart and I decided to hold off on the middle of the lesson he’d written up. That middle bit where he said to “put a pin in it” was about the use of xargs. I’m really glad we did skip it in the last installment. It’s a pretty useful concept […]

I don’t always make the time to pre-read the shownotes for Programming By Stealth but I never regret when I do make the time. That was especially true this week. In this installment, Bart Busschots takes us through his solution to the challenge from PBS 151, which was to print a “pretty” multiplication table using […]

This week’s Programming By Stealth wasn’t a heavy lift but I managed to get confused a couple of times anyway so expect lots of questions from me in this one. Bart started the show by telling us about a clever tip from listener Jill of Kent about how to detect when the Terminal talking to […]

When Bart and I recorded PBS 150 on Bash Script Terminal Plumbing, neither of us was happy with it. I got very confused in the middle, and Bart decided that his original strategy might have been flawed in which he assumed everyone had heard Taming the Terminal and remembered everything taught more than 4 years […]

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 […]
Continue readingCCATP #762 — Bart Busschots on PBS #147 – Bash Arrays
In this week’s episode of Programming By Stealth, Bart walks us through how to create, add to, and extract from arrays using Bash. It’s a very light episode, which I manage to drag out longer by making him slow down and dig into the syntax used for arrays. It’s not just me being dense (this […]
Continue readingCCATP #759 — Bart Busschots on PBS 145 of X — Shell Conditionals
Bart continues his miniseries on shell scripting by teaching us conditionals in the shell. In order to explain why conditionals are a bit odd in shell scripting, Bart first walks us through how it was originally done and then shows us the evolution to a much better method. It’s still weird, and many things are […]
