I just stumbled across a simple yet fun script I wrote over a year ago to animate your keyboard LEDs:
#!/bin/sh LED="setleds -L" SLEEP="sleep 0.2s" $LED -num -caps -scroll if [ "$1" = "-c" ] ; then exit 0 fi while [ 1 ] ; do $LED +num $SLEEP $LED +caps $SLEEP $LED +scroll $SLEEP $LED -num $SLEEP $LED -caps $SLEEP $LED -scroll $SLEEP done
It will simply pulsate the keyboard LEDs from left to right. Note that this script only works while logged into a tty — it does not work under X11.
how interesting, does this work on any keyboard? looks like fun
Yes, it works on both PS/2 and USB, as long as your keyboard has LEDs. If the LEDs are in a funny arrangement (like on a lot of laptops these days), then it may look strange!
