title: Cant import data into mongo database using mongoimport
body: <p>I can't import data into my existing database located on mongoDBAtlas. I installed and connected robomongo with mongoDBAtlas for working with atlas. </p>
  
  <p>I created new database <strong>jasper</strong> and collection <strong>User</strong> in robomongo then
  I created user.json file in my project where are stored my data.</p>
  
  <p>I followed tutorial on <a href="https://docs.atlas.mongodb.com/import/mongoimport/" rel="nofollow noreferrer">https://docs.atlas.mongodb.com/import/mongoimport/</a> - how to use mongoimport with mongodb. </p>
  
  <p>Here is my command, Im typing in terminal: </p>
  
  <pre><code>mongoimport --uri mongodb://Morty:&lt;PASSWORD&gt;@jasper-shard-00-00-mrihb.mongodb.net:27017/jasper?ssl=true&amp;replicaSet=jasper-shard-0&amp;authSource=admin --collection User --drop --file ./src/data/user.json --jsonArray
  </code></pre>
  
  <p>that give me an error: </p>
  
  <pre><code>[1] 40930
  [2] 40931
  -bash: --collection: command not found
  [2]+  Done                    replicaSet=jasper-shard-0

  2017-10-15T10:38:35.209+0200    try 'mongoimport --help' for more information       
  </code></pre>
  
  <p>If I run mongoimport  for <strong>localhost</strong> it works perfectly.</p>
  
  <p>Where should be the problem ?</p>
