title: is there a simpler way to update a Mongodb collection in just one line (in command line)?
body: <p>right now, i do this in command  line:</p>
  
  <pre><code>var obj = db.mycollect.find({id="231412"});
  obj.abc = 'new value';
  obj.save();
  </code></pre>
  
  <p>3 lines of code..</p>
  
  <p>is there a simpler way to do this?</p>
  
  <pre><code>e.g. db.mycollect.find({id=12345}).save({abc:'new value'});
  </code></pre>
