Just send curl -XGET 'localhost:9200'

And ElasticSearch will return its version in the respond, along with other info.

    This works only in a case where you have only one version of ElasticSearch, and it's actually listening on port 9200 instead of another port, and it's listening to localhost and not on some other interface. – Jenny D Apr 5 '16 at 14:17

    @JennyD you can also use $ES_HOME/bin/elasticsearch -v to get a version of specific Elasticsearch setup – Kirill Nov 28 '17 at 11:22
  • @Derp That is a lot more functional, yes. – Jenny D Nov 28 '17 at 11:24
  • In Windows use curl -XGET localhost:9200 – yu yang Jian Jul 3 '18 at 7:23
  • In OSX installed through brew. elasticsearch --version Version: 5.4.0, Build: 780f8c4/2017-04-28T17:43:27.229Z, JVM: 1.8.0_131 – Nanhe Kumar Oct 23 '18 at 22:02
