title: Jupyter commands work only with a dash (e.g. jupyter-kernelspec instead of jupyter kernelspec)
body: <p>I am using Jupyter with Anaconda3.</p>
  
  <p>My <code>Anaconda3\</code> and <code>Anaconda3\Scripts\</code> folders have been added to the <code>%PATH%</code> variable.</p>
  
  <p>Eventhough the <code>jupyter.exe</code> is in the <code>Scripts</code> folder above, Jupyter related commands don't work without a dash.</p>
  
  <ul>
  <li><p>For example:</p>
  
  <pre><code>jupyter kernelspec --version
  Error executing Jupyter command 'kernelspec': [Errno 'jupyter-kernelspec' not found] 2
  </code></pre></li>
  <li><p>The same command with a dash works:</p>
  
  <pre><code>jupyter-kernelspec --version
  5.2.2
  </code></pre></li>
  </ul>
  
  <p>And the same goes for <code>jupyter-notebook</code>, etc.</p>
  
  <p>Do I have to add anything else to my <code>%PATH%</code>? Am I missing something?</p>
  
  <p>I have opened an issue for this point on Github as well, but it didn't get any attention unfortunately: <a href="https://github.com/jupyter/jupyter/issues/381" rel="noreferrer">https://github.com/jupyter/jupyter/issues/381</a></p>
