I just learned:
https://github.com/ogham/exa the ls replacement has been replaced by https://github.com/eza-community/eza
ls
the exa repo says:
exa
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
