title: How do I pull changes from github repository to my local machine?
body: <p>I've seen several questions/answers very similar to this but still not sure I understand if they are what I need.  So accept my apologies if this was covered before by something similar.</p>
  
  <p>I have a private GitHub account with several repositories.  I created these from my mac, pushed them to GitHub and everything works great.</p>
  
  <p>From my Ubuntu desktop, I did a git clone and pulled a couple of the repositories to that desk top.  Now from Ubuntu, I make a change to a file, add it, commit it, and push it to GitHub.  </p>
  
  <p>Question:
  How (what command) on my mac do I use to pull that change down to my local repository so I get that change(s)?  UserName is JohnCowan, repo is sacnomadgolf.git</p>
  
  <p>Thanks for the help.</p>
