title: Shell script to copy files from one location to another
body: <p>I'm developing on a MAC and I'm very new to scripting on a MAC.</p>
  
  <p>Basically I'd like to have a script that can copy files from one location to another so I can run it in the terminal rather than having to copy the files manually. So, I wonder if anyone out there can provide me with a script that;-  </p>
  
  <p>Checks the content of the destination folder against that of the source folder and where there is a difference, copies the files from the source folder to the destination folder.</p>
  
  <pre><code>                 -OR IF THAT IS NOT POSSIBLE-
  </code></pre>
  
  <p>a script that simply copies files from one location to another.</p>
