Add `type`-builtin instead of `which`
Created by: LeonardKoenig
Description: which
is a remnant of csh and behaves on many shells differently, type
has since replaced it as a portable and standardized alternative, cf. https://unix.stackexchange.com/questions/85249/why-not-use-which-what-to-use-then
Proposed change: Add type
shell-builtin, possibly deprecate/remove which
.
