title: Create mongo change stream in the mongo shell
body: <p>MongoDB introduced <a href="https://docs.mongodb.com/manual/changeStreams/" rel="nofollow noreferrer">change streams</a> in their 3.6 release.<br>
  I wanted to implement mongo change stream in my code and wanted to understand how it works. I will implement using the java driver and it's pretty clear.
  But I wanted to know if there is there any way to open a change stream on in the mongo shell? Couldn't find much resources on that.</p>
