  <pre><code>&gt; /usr/bin/curl -s -XPOST localhost:9200/_bulk --data-binary "@/home/1003783/data/20161201.json"
  =&gt; {"took":9,"errors":false,"items":[{"index":{"_index":"ctlg_info","_type":"1002154","_id":"20161201","_version":2,"_shards":{"total":3,"successful":3,"failed":0},"status":200}}]}
  </code></pre>
  
  <p>When I run the curl command against elasticsearch, I do not want to see the above message. It seems to be a message from elasticsearch.</p>
  
  <p>Thank you.</p>
