> Since I never remember which one is which, a good way to check is using the utility `file`: `file $(which useradd)`

While we're here, can someone explain why `which` prints some locations, and for others the whole darn file? Like `which npm` prints the location; `which nvm` prints the whole darn file.

Are you sure that what is being printed is the contents of a file? And which shell are you using?

If your which command is a shell builtin, and nvm is a function, then you’re likely seeing the content of that function.
