streamlink:tldr:7fc19

This command launches the program called "streamlink" with specific parameters. Here is the breakdown of each part:

• streamlink: This is the name of the program that is being executed.
• --player=${mpv}: This is an option for the streamlink program. It sets the media player to be used for playback. In this case, the ${mpv} variable is being used, which suggests that the value of the mpv variable should be substituted here.
• ${example-com-stream}: This is another variable being used. It represents the URL of the stream from the website "example.com". The actual URL should be substituted here.
• ${best}: This is a variable that specifies the quality of the stream to be played. The value "best" suggests that the highest available quality should be chosen. Again, the value of this variable should be substituted here.

In summary, this command launches the "streamlink" program, specifies a media player, provides a stream URL, and selects the best available quality for playback.
