Here is how to use it with (X)Ubuntu.
Software. Install GNUPod.
apt-get install gnupod-toolsInstall iPod Shuffle DB Rebuilder (shuffle_db).
Download the script from the project website.Initialization. This only needs to be done once (or anytime you mess up the shuffle).
mount /dev/sda1 /media/ipod/The device file /dev/sda1 might differ on different machines.
gnupod_INIT -m /media/ipod/
cp rebuild_db.py /media/ipod/
Transfering Music is a four step process: mount; copy mp3s into the music directory; rebuild the database; umount.
mount -o exec /dev/sda1 /media/ipodAlternatives. You can transfer music to the Shuffle with GNUPod or GTKPod, but I like the shuffle_db better because it is very simple and because it maintains directory structure.
cp ~/music/songs /media/ipod/music/
/media/ipod/rebuild_db.py -l music
