I am looking for help in processing of those options: '-n' or '-p'
I understand what they do and how to use them.
But, I would like to use them with more than one file (and without any shell-loop; loading the 'perl' once.)

amqp-consume
AMQP-CONSUME(1) RabbitMQ C Client AMQP-CONSUME(1)
NAME
amqp-consume - Consume messages from a queue on an AMQP server
SYNOPSIS
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.
-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 successfully or not.
EXAMPLES
Consume messages from an existing queue "myqueue", and output the message bodies on standard output via cat:
$ amqp-publish -q myqueue cat
Bind a new exclusive queue to an exchange "myexch", and send each message body to the script myscript, automatically acknowledging them on
the server:
$ amqp-consume -A -e myexch ./myscript
