title: What does 'cd -' stand for?
body: <p>In a bash shell script today I noticed the below command at the end of the script. I know what is <code>cd</code> but I am unaware of the significance of a dash after it.</p>
  
  <pre><code>cd -
  </code></pre>
  
  <p>What does this mean? Google naively truncates the <code>-</code> so I am unable to find its answer.</p>
