The script retrieves images from Unsplash using a developer API key and sets them as the desktop background. It supports selecting a random picture, specifying a category such as “galaxy” or “landscape,” and automatically updating the wallpaper at a user‑defined interval. Command‑line options include displaying help, version information, and configuring the time between changes for the automatic mode.

It is a Node.js utility that can be installed globally via npm and run directly from a terminal. Users must first obtain an Unsplash developer ID, which the script stores for subsequent requests. The tool works with standard command‑line workflows and can be combined with process managers like forever to keep the automatic rotation running continuously.

The package is marked as stable and provides a minimal set of commands—`change` for a one‑time update, `auto` for timed rotation, and `key` for updating the API credentials—making it suitable for users who want a simple, scriptable way to keep their desktop wallpaper fresh with images from Unsplash.
