I'd guess that standard output is not defined when that script is run.
So it might be worth to set a file for that, like:
   echo "echoing from inside script lidclose.sh" >> /tmp/lidclose.log

What is critical here is that you would need it on a shell script, and
that doesn't work. (Thanks to Jochen for checking the file type!)
