So I think of the types as being grep "." *.hs :: String wc :: String -> Int -- ok, not really, but it shows the point better.

Every unix program has a standard input, even if it doesn't use it, so I would rather give this type to grep "." *.hs: grep "." *.hs :: a -> String You can run something like this p | echo bla | grep "." *.hs | wc even if it seems non-sensical. Best regards Tomasz
