What Does Homebrew Do?
1.Homebrew installs the stuff you need that Apple didn’t.
$ brew install wget
2.Homebrew installs packages to their own directory and then symlinks their files into /usr/local.
$ cd /usr/local
$ find Cellar
Cellar/wget/1.16.1
Cellar/wget/1.16.1/bin/wget
Cellar/wget/1.16.1/share/man/man1/wget.1
$ ls -l bin
bin/wget -> ../Cellar/wget/1.16.1/bin/wget
3.Homebrew won’t install files outside its prefix, and you can place a Homebrew installation wherever you like.
4.Trivially create your own Homebrew packages.
$ brew create https://foo.com/bar-1.0.tgz
Created /usr/local/Library/Formula/bar.rb
5.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!
6.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"
sha256 "52126be8cf1bddd7536886e74c053ad7d0ed2aa89b4b630f76785bac21695fcd"
def install
system "./configure", "--prefix=#{prefix}"
system "make", "install"
end
end
7.Homebrew complements OS X. Install your gems with gem, and their dependencies with brew. Homebrew
