Title: use `command -p pwd` to use the system default pwd

`command -p pwd` overrides any aliases a user might have set for `pwd`. In my case, I aliased `pwd` to copy the current directory to the clipboard. While this is an edge case, using `command -p pwd` would ensure aliases are ignored, without having to specify a path.
