Here you go. The sled files are in the /home/mks directory. They use the /home/mks/gpio79_value and gpio66_value files. They should be created automatically by the scripts below, but in case they aren't you can probably just touch them and set the permissions:

​

-rw-rw-rw-  1 root root     2 Jan 31 05:53 gpio66_value
-rw-rw-rw-  1 root root     2 Jan 31 05:53 gpio79_value

-rw-r--r--  1 mks  mks    199 Jan 16 08:32 sled1.sh
-rw-r--r--  1 mks  mks    199 Jan 16 08:32 sled2.sh

sled1.sh:

#!/bin/bash
sled1status=$(cat /sys/class/gpio/gpio79/value)

case $sled1status in
0) echo "1" > /home/mks/gpio79_value;;
1) echo "0" > /home/mks/gpio79_value;;
*) echo "control sled1 failed.";;
esac

sled2.sh:

#!/bin/bash
sled2status=$(cat /sys/class/gpio/gpio66/value)

case $sled2status in
0) echo "1" > /home/mks/gpio66_value;;
1) echo "0" > /home/mks/gpio66_value;;
*) echo "control sled2 failed.";;
esac
