rabbitmq

Usually work in Windows, but trying to setup RabbitMQ on my Mac. Can someone let me know what the line below does?

[ "x" = "x$RABBITMQ_NODE_IP_ADDRESS" ] && [ "x" != "x$NODE_IP_ADDRESS" ] && RABBITMQ_NODE_IP_ADDRESS=${NODE_IP_ADDRESS}

Specifically, I'm curious about the [ "x" = "x$RAB..."] syntax.
