implement unix pipes in haskell

I'm writing a mini shell and although I've got most of it planned out, one thing I'm not sure how to do is implement piping the o开发者_开发百科utput of one program as the input of another. Is there a sample or something that can point me in the right direction?


The RWH Book has a complete example of how to emulate piping in Haskell, IMO is one of the best examples of the book and it could be quite enlightening.

Good Luck.
