## What it is
z.lua is a command-line tool that speeds up filesystem navigation by tracking your most-used directories using a frecency algorithm. It is a fast, single-file Lua alternative to z.sh, autojump, and fasd, supporting bash, zsh, fish, PowerShell, and Windows cmd.

## Use cases
- jump to frequently visited directories quickly
- cd to a directory by typing partial path keywords
- replace cd ../../.. with a parent directory jump
- interactively pick a directory with fzf integration
- use autojump-style navigation on Windows cmd or PowerShell
- fast directory jumping on low-power devices like Raspberry Pi

## When to choose
- you want a faster z.sh/autojump/fasd alternative
- you need directory jumping across multiple shells and platforms
- you prefer a self-contained single-file tool with no dependencies
- you use fzf and want interactive directory selection

## When to avoid
- you don't want to install Lua on your system
- you need a GUI file manager rather than shell navigation
- you only navigate a small set of directories and don't need frecency tracking
