title: How to list packages used in conda create/install command?
body: <p>Suppose I use the following command to make an environment called env1:</p>
  <pre><code>conda create -n env1 matplotlib numpy ipython jupyterlab
  </code></pre>
  <p>How can I at a later time get a simple listing showing '<code>matplotlib</code> <code>numpy</code> <code>ipython</code> <code>jupyterlab</code>'? I know about the <code>conda -list</code> command, but it shows something much more detailed (all dependencies, etc..) than what I want. I checked all the commands shown in <a href="https://docs.conda.io/projects/conda/en/latest/commands/list.html" rel="nofollow noreferrer">this documentation</a> of conda's list command and none worked for me.</p>
  <p>I understand that packages can also be installed using conda's <code>install</code> command, and expect those would be listed as well.</p>
