Import settings file and refresh Domain Key via CLI

Hi!

I was wondering if there were some commands that could be used (a bash script most likely) that would allow me to load a settings.data file from the server which contains preconfigured settings, as well as a command to Refresh the Domain Key, as importing said data file manually overwrites the old Key for some reason (likely because I exported the settings file from a website with a Key already configured)

So basically I need help with 2 things.

1) How to import LScache settings via CLI
2) Is it possible to Refresh domain key via CLI

Appreciate all help and ideas in advance
