Using some long exa incantation risks alienating people that don't care about things like the latest trendy grep alternative

Exa is the latest, trendy ls alternative.

I don’t think you should remove the Exa example but you certainly should show how to use ls to do something similar for those people still living in the dark ages—ls was created in the 1970s and it hasn’t kept up with the times all that well [1].

I created an ‘ll’ alias for Exa using the Fish shell; obviously you make shell-appropriate aliases in Bash or Z shell:

    function ll
      exa --color always --long --no-user --no-permissions --all --icons $argv
    end
