Run just --list to see available recipes, then just <recipe> to run one.

01Command

Command
$ just --list

02What it does

just reads a justfile of named recipes and runs them with a clean shell, passing arguments as expected. Unlike make it is designed for commands rather than file timestamps, so it works well for test, lint, build and deploy shortcuts.
