title: Mongo db shell variable printing only once
body: <pre><code>&gt; var x = db.sampleDB.find();
  &gt; x
  </code></pre>
  
  <p>output:</p>
  
  <pre><code>{ "_id" : ObjectId("55d02ed690ddbaafbfe20898"), "name" : "aditya", "city" : "meerut" }
  </code></pre>
  
  <p>But if I print this variable again, it does not printing anything.
  and I am not able to print <code>x.name</code>?</p>
  
  <p>using ubuntu 14.04(db version v2.6.10)</p>
