title: How to set `pipenv shell` prompt to match the Terminal's PS1 prompt?
body: <p>I'm using <code>MacOS</code> and <code>bash</code>.</p>
  <p>I'm using <code>pipenv</code> for virtual environments and I really want to make the look of my virtual shell match the look of my standard shell.</p>
  <p>When I'm outside of <code>pipenv</code>, I set my <code>.bash_profile</code> so I could have the time, a green command prompt that shows the full path of my working directory and, if that directory has a git repo, it shows my current branch at the end.</p>
  <p>I've searched for the correct file to edit to get the same look for each new <code>pipenv</code> shell, but I'm not having any luck finding the right file to copy my profile preferences to.</p>
  <p>I'm wondering how I can set it up with my standard <code>PS1</code> terminal appearance (colors and current git branch, etc).</p>
