title: Changing directory in Google colab (breaking out of the python interpreter)
body: <p>So I'm trying to git clone and cd into that directory using Google collab  - but I cant cd into it. What am I doing wrong?</p>
  <blockquote>
  <p>!rm -rf SwitchFrequencyAnalysis &amp;&amp; git clone <a href="https://github.com/ACECentre/SwitchFrequencyAnalysis.git" rel="noreferrer">https://github.com/ACECentre/SwitchFrequencyAnalysis.git</a></p>
  <p>!cd SwitchFrequencyAnalysis</p>
  <p>!ls
  datalab/  SwitchFrequencyAnalysis/</p>
  </blockquote>
  <p>You would expect it to output the directory contents of SwitchFrequencyAnalysis - but instead its the root. I'm feeling I'm missing something obvious - Is it something to do with being within the python interpreter? (where is the documentation??)</p>
