Homebrew的使用

$ brew install wget

Homebrew installs packages to their own directory and then symlinks their files into /usr/local.

$ cd /usr/local
$ find Cellar
Cellar/wget/1.15
Cellar/wget/1.15/bin/wget
Cellar/wget/1.15/share/man/man1/wget.1

$ ls -l bin
bin/wget -> ../Cellar/wget/1.15/bin/wget

• Homebrew won’t install files outside its prefix, and you can place a Homebrew installation wherever you like.

Trivially create your own Homebrew packages.

$ brew create http://foo.com/bar-1.0.tgz
Created /usr/local/Library/Formula/bar.rb

It's all git and ruby underneath, so hack away with the knowledge that you can easily revert your modifications and merge upstream updates

$ brew edit wget # opens in $EDITOR!

Homebrew formulae are simple Ruby scripts:

class Wget < Formula
  homepage "https://www.gnu.org/software/wget/"
  url "https://ftp.gnu.org/gnu/wget/wget-1.15.tar.gz"
  sha1 "f3c925f19dfe5ed386daae4f339175c108c50574"

  def install
    system "./configure", "--prefix=#{prefix}"
    system "make", "install"
  end
end

• Homebrew complements OS X. Install your gems with gem, and their dependencies with brew.
