CCATP #773 — Bart Busschots on PBS 152B — Bash: xargs & Easier Arithmetic
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 […]

In this rather mind-bendy episode of Programming By Stealth, Bart Busschots takes into the weird world of POSIX special variables and options. He refers to some of them as being like handling nuclear power, at one point he suggests mind-altering drugs must have been involved in the design, and he even compares one of our […]

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 […]

This week our guest is Bart Busschots with Programming By Stealth 144. When last we recorded, Bart started teaching us the basics of shell scripting using Bash.

In order to start the rewrite, we need to understand the […]

We’re back in the saddle after a summer of “PBS Adjacent” installments. Our last real PBS was learning how to use Webpack to bundle a JavaScript library for sharing with the world. That was cool, but a lot of us want to use Webpack to bundle a web app we’ve written ourselves to include all […]
