Easy iPod Shuffle Syncer

README.md

These are easy to follow instructions, adapt them for your needs 😉.

1. (IMPORTANT) Create a directory ~/iPod
2. (IMPORTANT) Mount your iPod in /ipod
3. Place all of your songs/podcasts into ~/iPod/music

• Each (first level) directory/folder is one playlist

4. Run this script

WARNING: if you are in a case sensitive filesystem (very likely if you are using linux) the case of the directories matter.

#!/bin/bash

# DO NOT add the final slash on those ENV vars

MOUNT_DIR=/ipod
