Does anyone know how to redirect the output of a program, running from a bash script, to a named pipe IN NON BLOCKING MODE (having 'O_NONBLOCK' flag set)?

Open it as read-write?

mkfifo wormhole
your_program <>./wormhole

Any subsequent program that read the pipe won't receive anything. –  magnetik Jun 5 at 9:04

You can use a small program called ftee that is available in this StackOverflow anwser: http://stackoverflow.com/a/7620387/403614

As far as I know (and as far as my research went), there are no "bash only" solutions.
