Tree

Display directory structure in tree format

Prerequisite Check

Run this before proposing tree output:

command -v tree >/dev/null 2>&1 || tree --version

If tree is missing, surface that first and fall back to find or ls -R, noting that formatting and depth controls will differ.

Quick Start

1. Verify tree is available: tree --version or man tree
2. Establish the command surface: man tree or tree --help
3. Start with basic usage: tree [options] [input]
