Did you check the command I gave you previously? A simple shellscript that searches for the directory where resides a file that has the word "sleep_ind" in it, and then echo a zero to the file named "value" in the same directory...
devel-su (the password) leds=$(find /sys/devices/virtual/gpio -name name | xargs grep sleep_ind | cut -d ":" -f 1| sed -e "s/name/value/") echo "0" > $leds
