amqp-consume — Consume messages from a queue on an AMQP server


amqp-consume OPTION command args Description amqp-consume consumes messages from a queue on an AMQP server. For each message that arrives, a receiving command is run, with the message body supplied to it on standard input. amqp-consume can consume from an existing queue, or it can create a new queue. It can optionally bind the queue to an existing exchange. By default, messages will be consumed with explicit acknowledgements. A message will only be acknowledged if the receiving command exits successfully (i.e. with an exit code of zero). The AMQP ``no ack'' mode (a.k.a. auto-ack mode) can be enable with the -A option. Options -q --queue=queue name The name of the queue to consume messages from. If the --queue option is omitted, the AMQP server will assign a unique name to the queue, and that server-assigned name will be dixsplayed on stderr; this case implies that an exclusive queue should be declared. -e --exchange=exchange name Specifies that an exclusive queue should be declared, and bound to the given exchange. The specified exchange should already exist unless the --exchange- type option is used to request the creation of an exchange. -r --routing-key=routing key The routing key for binding. If omitted, an empty routing key is assumed. -d --declare Forces an exclusive queue to be declared, even when it otherwise would not be. That is, when a queue name is specified with the --queue option, but no binding to an exchange is requested with the --exchange option. Note: this option is deprecated and may be removed in a future version, use the --exclusive option to explicitly declare an exclusive queue. -x --exclusive Declared queues are non-exclusive by default, this option forces declaration of exclusive queues. -A --no-ack=routing key Enable ``no ack'' mode: The AMQP server will unconditionally acknowledge each message that is delivered, regardless of whether the target command exits suc‐ cessfully or not. -c --count=limit Stop consuming after the given number of messages have been received. -p --prefetch-count=limit Request the server to only send limit messages at a time. If any value was passed to --count, the value passed to --prefetch-count should be smaller than that, or otherwise it will be ignored. If -A/--no-ack is passed, this option has no effect. Examples Consume messages from an existing queue ``myqueue'', and output the message bodies on standard output via cat:" 10 $ amqp-publish -q myqueue cat Bind a new exclusive queue to an exchange ``myexch'', and send each message body to the script myscript, automati‐ cally acknowledging them on the server:" 10 $ amqp-consume -A -e myexch ./myscript See also librabbitmq-tools(7) describes connection-related options common to all the RabbitMQ C Client tools.
