Implement unix pipes in haskell

Question

I am writing a mini-shell, and although I have most of it planned, one thing that I do not know how to do is to implement the output of one program as the input of another. Is there a pattern or something that can point me in the right direction?

Answer 1

The RWH book has a complete example of how to emulate pipelines in Haskell, IMO is one of the best examples of the book, and it can be quite useful.

Good luck.
