Subject: listening on a fifo

I'm using the following to have a program listen on a fifo and take
action whenever input becomes available.  The fifo should be used like
a device under /dev, like:

	$ echo 'hello world' >fifo

Is there any better/nicer way?


fifo = 'foo'
`mkfifo #{fifo}` if not File.exists?(fifo) 

loop do
  f = File.open(fifo, File::RDONLY | File::NONBLOCK) 
  select [f]
  p f.read
end
