How to train your Bash

Have you ever been to a place where a Bash script had over 3000 lines and rendered your IDE unusable? I have. And I still have nightmares about that. There are different strategies to handle this - some people go to see their mamas, others start a new life in the mountains. But don’t lose hope. I want to show you that when you know some “dos and don’ts” and keep some rigor, your Bash script can be easy to write, read and refactor. It won’t surprise you with side effects when it’s run. I will argue that you can do a real programming in Bash! And if you’re crazy enough, it can even be functional. Don’t grow gray hair any more - come see how to train your Bash.
