`master` doesn't have any extra options. It simply displays the

2016-10-13 16:42:21 -04:00
|
|
|
master's node ID, bound IP address, and node name. For example:

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:
