How to update Xcode from command line
<p>I am trying to update Xcode from the command line.  Initially I tried running:</p>

<pre><code> xcode-select --install
</code></pre>

<p>which resulted in this message:</p>

<pre><code>xcode-select: error: command line tools are already installed, use "Software Update" to install updates
</code></pre>

<p>So the question remains, is there a way to update Xcode from the command line? </p>
