Hello,  
How do I return the TASK ID when submitting a POST request like:

```auto
POST _reindex?requests_per_second=115&wait_for_completion=true
{
  "source": {
    "index": "elb-2020.01.*",
    "size": 500
  },
  "dest": {
    "index": "elb-2020.01"
  },
  "script": {
    "lang": "painless",   
    "source": """
      ctx._source.index = ctx._index;
      def eventData = ctx._source["event.data"];
      if (eventData != null) {
        eventData.remove("realmDb.size");
        eventData.remove("realmDb.format");
        eventData.remove("realmDb.contents");
      }
    """
  }
}

```

i am basically writing a bash script and want to check to see if the task has been completed before proceeding.

any advice is much appreciated
