title: How do I write a BASH script to download and unzip file on a Mac?
body: <p>I need to create a bash script that will work on a mac.  It needs to download a ZIP file of a site and unzip it to a specific location.</p>
  
  <ol>
  <li>Download the ZIP file (<code>curl -O</code>)</li>
  <li>Unzip the files to a specific location (<code>unzip filename.zip path/to/save</code>)</li>
  <li>Delete the .zip file</li>
  </ol>
  
  <p>I need to make it so people can double-click the text file on their desktop and it will automatically run in terminal.</p>
  
  <p>How do I make it so that the user can double click the icon on the desktop and it will run?  What extension does the file need?</p>
