In the old days we all used to know all the ANSI control sequences off by
heart.  Nowadays you have it easy with curses and the like.  Not sure if
curses can be used to just use as many lines as you need rather than the whole
screen.  Perhaps it's over the top but you 0nly need to do it once.

The \r trick is the most common though, maybe you should try to get that
working.  Then squeeze all statuses onto 1 line eg:

File 1       File 2      File 3     File 4
  23%          45%        100%         0%\r  24%     etc.
