This command, id3v2 --list-tags ${filename1 filename2 ---}, is used to display the ID3 tags of one or more audio files. Let's break it down:

• id3v2 is the name of the command-line tool used to work with ID3 tags. It allows you to manipulate and retrieve information from audio files that use ID3 tags, which are typically found in MP3 files.

• --list-tags is an option or flag provided to the id3v2 command. This specific option instructs the tool to display a list of all available ID3 tags in the specified audio files.

• ${filename1 filename2 ---} represents the placeholder for file names or paths. The command is designed to accept multiple file names or paths as arguments. The --- is meant to indicate that more file names can be provided.

To use this command, you would replace ${filename1 filename2 ---} with the actual names or paths of the audio files that you want to retrieve ID3 tag information from. For example, if you have two audio files named "song1.mp3" and "song2.mp3" in the current directory, you would execute the command as: id3v2 --list-tags song1.mp3 song2.mp3. The tool will then display a list of the available tags found in each of the specified files.
