abook – Audiobook Merger Script

abook is a Bash script function that automates the process of merging multiple .mp3 files in the current directory into a single .m4b audiobook file. It uses ffmpeg and temporary file management for a streamlined experience.

📦 Features

• Automatically combines all .mp3 files in the current directory
• Outputs a .m4b file named after the current folder
• Temporary files are automatically cleaned up
• Simple help menu with -h or --help option

🛠 Requirements

• bash
• ffmpeg
• gmktemp (GNU mktemp or equivalent for temporary files)

📂 Usage

Step 1: Load the function in your shell

You can source the script or add the function to your .bashrc/.bash_profile:

source /path/to/abook.sh

Step 2: Run the command

Navigate to a folder containing MP3 files:

cd /path/to/mp3/files
abook

This will create a file called foldername.m4b in the same directory.

Help

abook -h

Displays usage instructions.

🧹 Cleanup

The script automatically deletes all temporary files it creates when it finishes or exits unexpectedly.

🧪 Example

Suppose you have a directory /audiobooks/MyBook with:

01_intro.mp3
02_chapter1.mp3
03_chapter2.mp3

Running abook in that directory creates:

MyBook.m4b
