I just learned:

https://github.com/ogham/exa the ls replacement has been replaced by https://github.com/eza-community/eza

the exa repo says:

exa is unmaintained, use the fork eza instead.
(This repository isn’t archived because the only person with the rights to do so is unreachable).

I didn’t read it all, but for the curious, looks like the story is here: [Question] Is this project still being actively maintained? · Issue #1139 · ogham/exa

hope everyone involved is OK, on to other projects
