That's what redirection is about: you assign the file handle to a
different file/device.

Please tell more about what does ``immediate access to stdout and
stderr'' mean.  What exactly are you trying to accomplish?

As for the keyboard input, this should be automatic: if you hook the
keyboard interrupt, you will see all the keystrokes, even those
pressed when the child program runs.  What you do with these
keystrokes is another matter; please describe what you want to do with
them in more detail.
