eyeD3 is a powerful command-line tool for managing ID3 tags in MP3 files. ID3 tags are metadata containers that store information such as the title, artist, album, and genre of an MP3 file. This tool is particularly useful for organizing large music libraries and ensuring that all metadata is consistent and accurate. While eyeD3 is commonly used in Linux environments, it is fully compatible with macOS, making it a valuable tool for Apple users who want to manage their MP3 collections efficiently.

In this article, we will cover how to install eyeD3 on macOS, basic commands for viewing and editing ID3 tags, and practical examples to help you get started.

Examples:

1. Installing eyeD3 on macOS:

   To install eyeD3 on macOS, you will need to use Homebrew, a popular package manager for macOS. If you don't have Homebrew installed, you can install it by running the following command in your Terminal:

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

   Once Homebrew is installed, you can install eyeD3 by running:

   brew install eyeD3

2. Viewing ID3

   To view the ID3 tags of an MP3 file, use the following command:

   eyeD3 example.mp3

   This will display all the metadata associated with the file example.mp3.

3. Editing ID3

   To edit the ID3 tags, you can use various options provided by eyeD3. For example, to change the title, artist, and album of an MP3 file, you can use:

   eyeD3 --title "New Title" --artist "New Artist" --album "New Album" example.mp3

4. Batch Editing:

   If you need to edit the metadata of multiple MP3 files at once, you can use a loop in the Terminal. For instance, to change the genre of all MP3 files in a directory to "Rock," you can use:

   for file in *.mp3; do eyeD3 --genre "Rock" "$file"; done

5. Removing ID3

   If you need to remove all ID3 tags from an MP3 file, you can use the following command:

   eyeD3 --remove-all example.mp3
