ezgh queues ack <receipt-handle>…Acknowledge received messages: each is deleted, and isn’t received again. Name them by the receipt handles their receive printed (up to 10 at a time, any queue). A handle is stale once its message was received again, acknowledged, moved to a dead-letter queue or expired: the message may then be handled twice. Receipt handles are their own credential: no login is needed or sent.
