List all indexes on ElasticSearch server?

Question

I would like to list all indexes present on an ElasticSearch server. I tried this:

curl -XGET localhost:9200/

but it just gives me this:

Answer 1

_stats/indices gives the result with indices.

$ curl -XGET "localhost:9200/_stats/indices?pretty=true"
{
  "_shards" : {
    "total" : 10,
    "successful" : 5,
    "failed" : 0
  },
  "_all" : {
    "primaries" : { },
    "total" : { }
  },
  "indices" : {
    "visitors" : {
      "primaries" : { },
      "total" : { }
    }
  }
}
