How to scramble a playlist ?

[Lothar Behrens]

Great,

that works. Now I have a random jukebox with just one click (with a  
desktop file).

Here is my script to get it working onto my bluetooth device:

#!/bin/sh
killall -SIGQUIT mplayer
/home/root/setup-bluetooth-audio.sh
rm playlist-sorted.m3u
rm playlist.m3u
find /media/card/Musik -name "*.mp3" > /home/root/playlist-sorted.m3u
/home/root/scramble.py /home/root/playlist-sorted.m3u > /home/root/ 
playlist.m3u
mplayer -ao alsa:device=bluetooth -playlist /home/root/playlist.m3u &
#mplayer -ao alsa:device=bluetooth http://yp.shoutcast.com/sbin/tunein-station.pls?id=2408
sleep 3
renice -19 `ps ax | grep mplayer | grep -Ev "grep|Unknown" | awk --  
'BEGIN {}{ print $1;}'`


setup-bluetooth-audio.sh:

#!/bin/sh
# Your device
export DEVICE=XX:XX:XX:XX:XX:XX

/etc/init.d/bluetooth stop
/etc/init.d/bluetooth start

sleep 1
passkey-agent --default 0000 &

sleep 1
echo Create bonding
dbus-send --system --type=method_call --print-reply --dest=org.bluez / 
org/bluez/hci0 org.bluez.Adapter.CreateBonding string

sleep 1
echo Activating service audio
dbus-send --system --print-reply --dest=org.bluez /org/bluez  
org.bluez.Manager.ActivateService string:audio

sleep 1
echo Creating device
dbus-send --system --type=method_call --print-reply --dest=org.bluez / 
org/bluez/audio org.bluez.audio.Manager.CreateDevice

sleep 1
echo Connecting sink
dbus-send --system --type=method_call --print-reply --dest=org.bluez "/ 
org/bluez/audio/device0" org.bluez.audio.Sink.Connec
