Elastic Stack Elasticsearch
1

how do I get rid of these indices?

# curl --silent --request GET $ELASTICSEARCH_URI/_cat/indices | grep metadata
green open %{[@metadata][beat]}-2018.02.20                         IVbWWsxTRiSDZCNNb8VDAw 5 1          1         0   36.3kb   18.1kb
green open %{[@metadata][beat]}-2018.02.21                         av3uixdMTriA83fx1Tuadg 5 1         70         0    1.4mb  784.1kb
green open %{[@metadata][beat]}-%{[@metadata][version]}-2018.02.21 Cbg3LZ_JRa23rkvZgzvyHg 5 1          7         0  202.7kb  101.3kb

I tried to follow Delete Index | Elasticsearch Reference [6.2] | Elastic, but that did not work for me:

# curl --verbose --request DELETE 0:9200/_cat/%{[@metadata][beat]}-2018.02.20
curl: (3) [globbing] nested brace in column 15
#

Please advise.

I was able to figure it out)

# curl --verbose --request DELETE $ELASTICSEARCH_URI/%25%7B%5B%40metadata%5D%5Bbeat%5D%7D-2018.02.20?pretty
