DESCRIPTION

rxqueue is a utility that provides access to the Regian Rexx external queue daemon (rxstack). It acts as a filter by placing lines onto a queue via stdin or a single line with the -t or --text switches. Lines can be pulled off the queue to stdout

-D, --debug: Turns debugging on -t string, --text string Places the single line specified in string onto an optional queue in the order specified by /fifo or /lifo
queue: The name of the queue to use. Format is queuename[@machine][:port]. If not specified the queue name used is SESSION on localhost using the default port.

ACTIONS

/fifo: Stacks the contents of stdin onto the queue in first in, first out order.
/lifo: Stacks the contents of stdin onto the queue in last in, first out order.
/clear: Removes all lines currently stacked in the queue.
/pull: Extracts the next line from the queue to stdout and removes it from the queue.
/queued: Returns the number of lines stacked on the queue to stdout
