## What it is
Zsh (the Z Shell) is a Unix shell written in C, designed for interactive use and also usable as a powerful scripting language. It is a feature-rich alternative to bash with advanced tab completion, line editing, and extensive customization options.

## Use cases
- replace bash as my default interactive shell
- scripting language for unix automation
- shell with advanced tab completion
- customize my terminal prompt and keybindings
- run shell scripts with posix-compatible features

## When to choose
- you want a highly customizable interactive shell with powerful completion and globbing
- you need a scripting shell with features beyond bash
- you use frameworks like oh-my-zsh or prezto

## When to avoid
- you need strict POSIX sh compatibility for portable scripts
- your environment or tooling assumes bash specifically
- you want a minimal shell with a tiny footprint

## Facets
- artifact type: application
- maturity: active
- function: interpreter, cli, developer-tools
- domain: developer-tools, operating-systems
- platform: bsd, cross-platform, cli
- tags: shell, zsh, unix-shell, scripting, interactive-shell, terminal, command-line, linux, macos
