Time for action — installing Homebrew
We are going to use Terminal to download Homebrew and install it onto our computer.
- Open Terminal.
- Type the following commands into Terminal, pressing Enter after each line:
sudo mkdir -p /usr/local sudo chown -R $USER /usr/local curl -Lf http://github.com/mxcl/homebrew/tarball/master | tar xz -- strip 1 -C/usr/local - Terminal will respond with a progress bar and show you how the installation process went. When the installation is complete, you will receive a success message, and you will have control of the Terminal again.
What just happened?
We added the directory /usr/local, which is where Homebrew will save all of its files. Then we made sure that the folder was owned by us (the current user). We then installed Homebrew using a cURL statement to grab the repository from Github (I'll cover cURL later in this chapter; we are going to use it quite a bit). After grabbing the repository, it was unzipped, using the command line function tar, and placed into the /usr/local folder.
