gnu-which

brew install gnu-which v2.25 GPL-3.0-or-later

GNU implementation of the which command that locates executables in your PATH.

Why you might care

Drop-in replacement for the BSD which found on macOS; offers more features like listing all matches (not just the first) and better POSIX compliance. Useful if you need portable shell scripts or prefer GNU semantics.

Caveats

GNU "which" has been installed as "gwhich".
If you need to use it as "which", you can add a "gnubin" directory
to your PATH from your bashrc like:

    PATH="$HOMEBREW_PREFIX/opt/gnu-which/libexec/gnubin:$PATH"
