What is the difference between "type" and "which" when locating a command?

A "type" reports how a command name would be interpreted by the shell (alias, function, builtin, or external file), while "which" searches $PATH for an external executable matching the name, often missing aliases, functions, and builtins B They are exactly the same and always return identical results C "which" only works for builtins, while "type" only works for external commands D "type" permanently changes a command's location on disk
