If I'm remembering correctly, miniunix didn't have pipes. The shell faked
it by taking the output of the first program into a file and then using it
as the input for the second.
Didn't really multitask anyhow, so it was pretty much fine.

doesn't have pipes, but you can simulate them.
Is this a SCO speciality, or are there other UNIXes like that?
Does it not even have pipe() in its libc?
