Running scrpt at wake

How can I run a shell script when my kodi (LibreELEC) box wakes from sleep?

I don't have a file called /storage/.config/sleep.conf.d/99-sample.power.x

I have a README & sleep.conf.sample

I created a file in that directory called 99script.sh. Permission is 755. The script redirects the output of date to a file. But nothing happens after the system wakes up.

What am I missing?

I'm assuming it's supposed to be the /storage/.config directory, the dot is missing. I'm also assuming that anything in that directory that has execute permission will be executed.

#!/bin/sh

echo "Hello World" >> /storage/test.txt
date >> /storage/test.txt

case "$1" in
   pre)
     # <do something on suspend>
     ;;
   post)
     # <do something on resume>

     echo "Waking up" >> /storage/test.txt
     date >> /storage/test.txt
     ;;
esac

/storage/test.txt is never created after a sleep/wake or reboot. Shouldn't myscript.power run whenever there is a power change?

Fixed. Had a typepo. Thanks for your help
