Dune is a shell designed for powerful scripting. Think of it as an unholy combination of bash and 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!
Yeah it is just my terminal emulator and this is specifically a bash+lisp shell. That wouldnt prevent me from attempting to use it the same on my first try like the special boi I am.
Kitty is the terminal emulator, the program that provides an interface. The shell you are using if you haven't changed anything is probably bash. So you would use duneshell instead of bash, but still in kitty
