Question

When you define a bash function you can call bash commands with command command.

function ls() {
  clear
  command ls "$@"
}

How would you pipe commands in bash function?

e.g.

function ls() {
  clear
  command ls "$@" | head
}

EDIT: The output would be OK, but there is --color=auto. Look here

Answer 1

Try this in your ~/.bashrc

function ls() { clear ; builtin ls "$@" | head ; }

It’s similar to the function you have already but with the inclusion of builtin, it guarantees not to get stuck in a loop calling itself. Hope this works!

EDIT: It should be noted that any colour information produced by ls with the --color=auto option won’t be carried through the pipe to head.
