[[cat-master]]
== Master
`master` doesn't have any extra options. It simply displays the
master's node ID, bound IP address, and node name.
[source,shell]
--------------------------------------------------
% curl 'localhost:9200/_cat/master?v'
id ip node

--------------------------------------------------
This information is also available via the `nodes` command, but this
is slightly shorter when all you want to do, for example, is verify
all nodes agree on the master:
[source,shell]
--------------------------------------------------
% pssh -i -h list.of.cluster.hosts curl -s localhost:9200/_cat/master
