Installing Homebrew on Mac OS X

Homebrew is a free and open-source (FOSS) package management system that is available for OS X/macOS systems. Homebrew makes extensive use of GitHub to expand the support of several packages through user contributions. The software was written by Max Howell in 2009; as of July 2016 there was a team of twelve developers maintaining the software. You can install it by opening a Terminal window and issuing the command /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)". I recommend putting the sudo command at the beginning of the command, so you won't be prompted so many times to provide the password for your account during the installation, i.e., sudo /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)". If you don't, you will see the output and password prompts shown below, which shows the directories being created and the file permissions being set.
