title: How to keep zsh running after command execution?
body: <p>I've been using this <a href="https://unix.stackexchange.com/a/123192">bash stanza</a> to start a new shell with my python virtual environment.</p>
  <pre><code>bash -i &lt;&lt;&lt; 'source venv/bin/activate; exec &lt; /dev/tty'
  </code></pre>
  <p>Naively, I translated it to zsh:</p>
  <pre><code>zsh -i &lt;&lt;&lt; 'source venv/bin/activate; exec &lt; /dev/tty'
  </code></pre>
  <p>It seems that my activate script is not run when this zsh stanza is invoked. How do I achieve the same functionality?</p>
