.Sh DESCRIPTION
.\" ------------------------------------------------------------------
.Nm
is a command line tool that provides commands used to manage queues,
mainly member handling for quorum queues.
See the
.Lk https://www.rabbitmq.com/quorum-queues.html "RabbitMQ quorum queues guide"
and
.Lk https://www.rabbitmq.com/ha.html "RabbitMQ classic mirrored queues guide"
to learn more about queue types in RabbitMQ.

.Sh OPTIONS
.\" ------------------------------------------------------------------
.Bl -tag -width Ds
.It Fl n Ar node
Default node is
.Qq Pf rabbit@ Ar target-hostname ,
where
.Ar target-hostname
is the local host.
On a host named
.Qq myserver.example.com ,
the node name will usually be
.Qq rabbit@myserver
(unless
.Ev RABBITMQ_NODENAME
has been overridden).
The output of
.Qq hostname -s
is usually the correct suffix to use after the
.Qq @
sign.
See
.Xr rabbitmq-server 8
for details of configuring a RabbitMQ node.
.It Fl q , -quiet
Quiet output mode is selected.
Informational messages are reduced when quiet mode is in effect.
.It Fl s , -silent
Silent output mode is selected.
Informational messages are reduced and table headers are suppressed when silent mode is in effect.
.It Fl t Ar timeout , Fl -timeout Ar timeout
Operation timeout in seconds.
Not all commands support timeouts.
Default is
.Cm infinity .
.It Fl l , Fl -longnames
Must be specified when the cluster is configured to use long (FQDN) node names.
To learn more, see the
.Lk https://www.rabbitmq.com/clustering.html "RabbitMQ Clustering guide"
.It Fl -erlang-cookie Ar cookie
Shared secret to use to authenticate to the target node.
Prefer using a local file or the
.Ev RABBITMQ_ERLANG_COOKIE
environment variable instead of specifying this option on the command line.
To learn more, see the
.Lk https://www.rabbitmq.com/cli.html "RabbitMQ CLI Tools guide"
