@gjscheer-ucd This is definately a problem with grass and not the script. It's easy to see simply by trying to run d.mon -l . I would suggest using the most up-to-date grass package, as described in https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update

I would even suggest upgrading to 7.8, but at the very least 7.6.
