I know it's not Christmas, but I accidentally wrote this script after reading this thread. It will randomly switch on and off random LEDs. #!/bin/bash cd /sys/class/leds LEDS=(*) ONOFF=('none' 'default-on') while true ; do LED=${LEDS[$((0 + $RANDOM % ${#LEDS[@]} ))]} VALUE=${ONOFF[$RANDOM % 2]} echo $VALUE > ${LED}/trigger sleep 0.1 doneby antrew - Debian
