title: How do I upgrade Bash in Mac OSX Mountain Lion and set it the correct path?
body: <p>since Mountain Lion still uses the old bash 3.x, I was wondering if there is a good tutorial (or if somebody could post one here) on how to upgrade bash to the latest version. Also, it would be helpful to know how to set the path so that it can be used in terminal.</p>
  
  <p>Thanks in advance</p>
