You can use expect to do this, if you know what the output of
the child will be just before it's waiting for IO.
This is the D lib I've written to do this:

It's not wonderful or anything, but it works :)
Thank you, good decision. Maybe I will use the idea. But how to
detect that "cat" (without arguments) waits input, if it nothing
prints?
