If the file is opened in text mode it will stop at the first EOF
character in the output.  I imagine that that was the problem with
openFile.

$ is just a low precedence right associative function application.  It's
mainly used to avoid parentheses.  It's definition is f $ x = f x.  You
can change something like f (g (h x)) into f $ g $ x.
