For clearing the screen, try 'Ctrl-l' (lowercase L)

A quick lookup suggests fish handles some of these differently than bash (apparently fish clears the buffer with this shortcut, so your scroll back is gone?).

There are a quite a few of these for anyone interested: https://kapeli.com/cheat_sheets/Bash_Shortcuts.docset/Conten...

I would do

  alias ls "exa"
  alias ll "exa -ll"

That way you get the nice shorter output which comes in handy for piping ls things like:

  ls -d | xargs ls

Lists the files in subdirectories.

good idea - thank you!
