If you tap the `homebrew-dupes` repository, you will get updates in the future:

    brew tap homebrew/dupes
    brew install grep

Are there any other utils worth installing from that tap? Awk? OpenSSH?

The repository with all of the formulas is here: https://github.com/homebrew/homebrew-dupes

The two I end up using semi-frequently are gcc and apple-gcc, for those projects that Clang just won't compile.
