Thanks. At first glance, I only found one issue with the bats tests. Let's see what a CI rerun will show.

Should this be renamed to --replace? Seems more obvious to me

I also think --replace would be better than --force. Once used, it wouldn't ignore any errors, it just replace the quadlet. What do you think, @Luap99?

[Luap99]

I am fine with naming this --replace

Code LGTM. I think the test could be improved a bit to verify that it isn't appending to the existing file

Code LGTM. I just have one question regarding the tests.
