amqp-declare-queue
AMQP-DECLARE-QUEUE(1) RabbitMQ C Client AMQP-DECLARE-QUEUE(1)NAME
amqp-declare-queue - Declare (create or assert the existence of) a queue on an AMQP server
SYNOPSIS
amqp-declare-queue [OPTION...] [-d] {-q queue name}
DESCRIPTION
amqp-declare-queue attempts to create a queue on an AMQP server, and exits. If the empty-string is supplied as the queue name, a fresh
queue name is generated by the server and returned. In all cases, if a queue was successfully declared, the (raw binary) name of the queue
is printed to standard output, followed by a newline.
OPTIONS -q, --queue=queue name
The name of the queue to declare. If the empty string is supplied, a fresh queue name is generated by the server.
-d, --durable
Causes the queue to be declared with the "durable" flag set. Durable queues survive server restarts. By default, queues are declared in
"transient" mode.
EXIT STATUS
If the queue was successfully declared, the exit status is 0. If an error occurs, the exit status is 1.
EXAMPLES
Declare the durable queue "myqueue", and display the name of the queue on standard output:
$ amqp-declare-queue -d -q myqueue
myqueue
Declare a fresh, server-named transient queue, and display the name of the queue on standard output (use amqp-delete-queue(1) to delete it
from the server once you're done):
$ amqp-declare-queue -q ""
