List of countreis

[Hex-99]

Is there a standard for the countries. I am unable to get a list using the container on a QNAP NAS.
I am using a compose file.
It works well with a guessed country but I would like to know what string patterns the countiries are in so that I can clone and create seperate containers and start\stop as necessary:

[] # docker run --rm bubuntux/nordvpn sh -c "nordvpnd & sleep 1 && nordvpn countries"
