id3tag:tldr:64c3d

The "id3tag" command here is likely a command-line tool used to modify the ID3 tags of an MP3 file. ID3 tags store metadata information, such as the artist name, song title, and more, within an MP3 file.

In this specific command, the following options and parameters are used:

--artist=${artist}: This option is used to specify the artist name for the MP3 file. The value of ${artist} is likely a placeholder that should be replaced with the actual artist name.

--title=${title}: This option is used to specify the title of the MP3 file. The value of ${title} is likely a placeholder that should be replaced with the actual title.

${filename-mp3}: This parameter is the name of the MP3 file that you want to modify the ID3 tags for. It is also likely a placeholder that should be replaced with the actual filename (including the .mp3 extension).

Overall, when running this command with the proper values for ${artist}, ${title}, and ${filename-mp3}, it will update the artist and title ID3 tags of the given MP3 file.
