Installing Homebrew on OS X

It's on the top of the Homebrew homepage.

From a Terminal prompt:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

The command brew install wget is an example of how to use Homebrew to install another application (in this case, wget) after brew is already installed.

Edit:

Above command to install the Brew is migrated to:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Check if Xcode is installed or not:

$ gcc --version

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

$ brew doctor

$ brew update

I might be late to the party, but there is a cool website where you can search for the packages and it will list the necessary command to install the stuff. BrewInstall is the website.

However you can install wget with the following command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install wget

Hope this helps :)
