 I've only used System V queues. Neither work like ActiveMQ.

I was never particularly interested in the nitty gritty, when I say I used ActiveMQ, I meant I used a wrapper API that used ActiveMQ, I think JMS. I generally liked to decouple my software development from specific implementations. It made my skills more transferable, less dependent on a specific development stack.
So, for me all queues tended to be just Enqueue/Dequeue, FIFO, data structures. The queue provider was mainly to shield me from the complexity of dealing with monitoring and reliability issues involved in handling a remote service.
I was just curious when this thread started commenting on what pipes were and I realised I had never programmed them, and hence gained a proper understanding. That has a knock on effect that I don't really understand the behaviour of programs which do use pipes. I'm presuming bash commands uses pipes.
