Turns out to be an interesting discussion about modularity. It's probably a good approach even for a one liner in a script.

Indeed, use zsh more. It's good... or at least better.

This can come in handy for automated tests which need to be ran from within a shell.

Looks like an interesting tool to try. History is an important part of the shell experience.

OK... didn't know about zmv. This looks really cool, I'll add it to my tool belt.

Nice tool to spice up your interactive shell scripts.

Interesting dive into history explaining why we had the x hack in shell script. Interestingly it was still relevant all the way to 2015 at least...
