title: Creating tar file and naming by current date
body: <p>I'm trying to create a backup script in bash, to tar the contents of a folder and move the resulting file somewhere, but I don't really know how to do it.</p>
  
  <pre><code>#!/bin/bash
  name="$date +"%y-%m-%d""
  tar -zcvf $name code
  </code></pre>
  
  <p>But the result is that the file is just named <code>+%y-%m-%d</code>. How can I change the script to name the file by the date as intended?</p>
  
  <p>Intended output: <code>2013-08-29.tar</code></p>
