Zsh

Part 2: A comprehensive reference covering every glob pattern from basic wildcards to advanced features like brace expansion and extended globs. Learn the rules that apply everywhere.

Glob patterns are everywhere - .gitignore, shell wildcards, build configs - yet most developers learn them by accident through copy-paste. Here’s why glob deserves explicit teaching.

Part 4: Learn how ZSH completions work under the hood. Build custom completions for your scripts, understand _arguments and completion contexts, and make tab completion actually useful.

Everyone uses Powerlevel10k, but do you understand how that fancy prompt actually works? Learn the ZSH primitives behind instant git status, command timing, and async rendering.

Started with Bitwarden-only shell scripts. Needed to support 1Password and pass without breaking anything. Built a shell abstraction layer, then ported it to Go. Same interface, three backends, zero breaking changes.

Complete guide to ZSH hooks: automate prompts, time commands, activate virtualenvs on cd, and filter secrets from history–without slowing down your terminal.

ZLE lets you create custom keybindings that manipulate your command line. Learn the fundamentals, build practical widgets (insert git branch, fuzzy file search), and understand how fzf integrates with ZSH.

Start on Mac, continue on Linux–same Claude conversation. Plus integrated AWS/Rust/Go/Python tools, extensible hooks, multi-vault secrets, and modular architecture. A framework, not just dotfiles.
