I’ve started a blog exclusively about the astonishingly powerful Z shell.
Check it out here: Focus on Zsh.
The goal is to find some of the more interesting and complex examples of Zsh code, and to break them down, explaining them line by line. Despite having worked with Zsh for many years (over a decade), I consider that I’ve barely scratched the surface of what it can do, and, not finding many instructive Zsh resources, have decide to create one.
Please take a look, and I look forward to your feedback.
