    I don't understand what you are asking here. The program that you posted
    in your original posting did *not* _redirect_ anything to the screen;
    rather the behaviour of the programs involved (cat, echo) write their
    output to standard output (per default "the screen"). So you have to
    redirect the output explicitly to a file.

    In general, if your_program writes its output to standard out...

    # only to stdout
    your_program

    # only to your_file
    your_program >your_file

    # to stdout and to your_file
    your_program | tee your_file

    # suppress any stdout output
    your_program >/dev/null

    Substitute your_program by the compound command of your original posting:

    { # whatever was here...
    } >your_file
