title: Python - Unix commands not recognized in Jupyter
body: <p>I have installed Git Bash, python 3.6 and Anaconda for the course which requires me to use Unix commands within Jupyter, such as !ls, !cat, !head etc.
  However, for each of these commands I get (e.g.):</p>
  
  <blockquote>
    <p>'ls' is not recognized as an internal or external command,
    operable program or batch file.</p>
  </blockquote>
  
  <p>I am using Windows 10. What can I do to be able to proceed with the course? 
  Thanks!</p>
