Control audio devices supporting the Linkplay API, from the comfort of your shell.
Supports UPnP auto-discovery, so you don't even have to know your device's IP address.

pip install linkplay-cli

After installing, run linkplay-cli -h to get started.

(Requirement: Python 3.6+)

The installed script is probably not in your PATH.
Run pip install with the -v flag to find out the script's directory, and make sure that it's in your path.

This CLI utility is a wrapper around the Linkplay API, which may not work in all situations.
For example, most commands won't work when the audio source is YouTube playing from your browser.
