[Haskell-beginners] [IO String] to IO [String]

[Ovidiu D]

My problem with interact was that it doesn't give me the line when the user
hits enter but instead it gives me all the lines at once when stdin is
closed (unless I did something wrong)

The other problem is that I want to stop the command processing when the
user types the command "exit" and it seems interact can't do that.
