  <p>I've tried the following:</p>
  
  <pre><code>docker rmi $(docker images | grep "^&lt;none&gt;" | awk "{print $3}")
  </code></pre>
  
  <p>And the following:</p>
  
  <pre><code>docker rmi $(docker images -f "dangling=true" -q)
  </code></pre>
  
  <p>Get the following error:</p>
  
  <pre><code>docker: "rmi" requires a minimum of 1 argument.
  See 'docker rmi --help'.
  
  Usage:  docker rmi [OPTIONS] IMAGE [IMAGE...]
  
  Remove one or more images
