title: Changing to remove path from environment variable PATH
body: <p>I'm trying to use a command line implementation to change the <code>PATH</code> environment variable to remove a path, so I don't have to manually remove it on a bunch of machines.</p>
  
  <p>I have found this, which I can't seem to get it to work:</p>
  
  <pre class="lang-none prettyprint-override"><code>%Path:str1=str2%
  </code></pre>
  
  <p><code>str1</code> is the path and <code>str2</code> is null, which I'm not sure how to set it to null on the command line.</p>
  
  <p>If there is another way, I would be glad to give it a try.</p>
