Say what?

I use \r when generating output to a terminal when I want to update
the current line of output instead of writing a new line.  E.g. for
tracking progress in my programs.

(As a line terminator followed by \n, it would have no effect though.)

If I haven't seen further, it is by standing in the footprints of giants
