title: No man page for the cd command
body: <p>Ubuntu Linux 15.10 - I just noticed that there is no man page for <code>cd</code></p>
  
  <p>This seems a bit strange.</p>
  
  <p>I tried:</p>
  
  <pre><code>man cd
  </code></pre>
  
  <p>at the cmd line and I get back</p>
  
  <pre><code>No manual entry for cd
  </code></pre>
  
  <p>I was trying to find documentation on </p>
  
  <pre><code>cd -
  </code></pre>
  
  <p>which is super-handy for flipping between the last dir and the current dir</p>
  
  <p>and <code>cd --</code></p>
  
  <p>which seems to be an alias for</p>
  
  <pre><code>cd ~
  </code></pre>
  
  <p>Am I missing something very obvious here, or should the man page be present?</p>
