Bash Script To Convert Folder Of Music To MP3

This is a simple bash script you can use to quickly convert a folder of music in AAC or FLAC into MP3 for use on a mobile device or small storage. To accommodate different input formats simple change the file suffix in the first line and the name variable regular expression from ‘mp4’ to ‘m4a’ or ‘flac’, etc. To use, copy/paste the script into a file within the folder to be converted and save it, then $chmod +x the_file_name and run the script ./the_file_name
The Script:

#!/bin/bash
for f in *.mp4
do
    name=`echo "$f" | sed -e "s/.mp4$//g"`
    ffmpeg -i "$f" -vn -ar 44100 -ac 2 -ab 320k -f mp3 "$name.mp3"
done

This script relies upon ffmpeg compiled with mp3 support (lamemp3).
