## add Homebrew to $PATH
You shouldn’t.

Homebrew intentionally keeps /usr/local/bin after /usr/bin in the path for maximum compatibility. Reversing the order of these directories in PATH by editing /etc/paths would mean that all programs anywhere on the system, no matter how they were started, will get the Homebrew version of a command. But some may specifically expect Apple’s version, or just not be able to use a newer version, etc.

How to preserve this principle and still get the Homebrew-installed version of git? As the saying goes, all problems can be solved with a layer of indirection (except having too many layers of indirection). — Or in this case, as it turns out, two layers.

Specifically, it’s been part of my Unix habits to have a ~/bin directory which I put at the start of my PATH. This is one of the first bits in my .bashrc:

    case ":$PATH:" in
      *:$HOME/bin:*) ;;     # do nothing if $PATH already contains $HOME/bin
