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

I use the _stats/indexes endpoint to get a json blob of data and then filter with jq.

curl 'localhost:9200/_stats/indexes' | jq '.indices | keys | .[]'

"admin"
"blazeds"
"cgi-bin"
"contacts_v1"
"flex2gateway"
"formmail"
"formmail.pl"
"gw"
...

If you don't want quotes, add a -r flag to jq.

Yes, the endpoint is indexes and the data key is indices, so they couldn't make up their minds either :)

I needed this to clean up these garbage indices created by an internal security scan (nessus).

PS. I highly recommend getting familiar with jq if you're going to interact with ES from the command line.
