Dune is a shell designed for powerful scripting. Think of it as an unholy combination of
bashand Lisp.You can do all the normal shell operations like piping, file redirection, and running programs. But, you also have access to a standard library and functional programming abstractions for various programming and sysadmin tasks!
So you can keep Kitty, just swap the shell you have it start by default (probably not a good idea to swap to this system-wide)
I know just enough about Linux (arch BTW) to get myself in trouble so idk if that would be a good idea.
