Further to the other responses, there is a thread here which has similar
issues.
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/336718
.
In particular:
.
1. Similar to Tim Hunter's suggestion:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/336734
... to show progress in a "console" box I just repeatedly use (every
second):
  print 13.chr + "text to show progress"
This - and presumably Tim Hunter's code - runs under Linux and Windows.
Actually I think I prefer Tim Hunter's formulation. (It's OK for me to say
that because the post just above was from me!)
.
2. If you want "multi line" changes this post uses curses and - apparently -
works on both Linux and Windows.
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/336742
... This is based on the "hello.rb" example in the following place on my
Win32 Ruby installation:
  C:/ruby/src/ruby-1.8.6-p111/ext/curses

require "curses"
include Curses

init_screen
puts '##### screen size(?): lines, cols:', lines, cols
puts 'about to display text'
sleep 2

begin
  crmode
  setpos( 8, 13 )
  addstr("display text which we will partly over-write later")
  refresh
sleep 2
  setpos( 3, 40 ) ; addstr("display some text") ; refresh
  setpos( 8, 40 ) ; addstr("PARTLY") ; refresh
  setpos( 8, 32 ) ; addstr("W") ; refresh
  20000.times do | k |
  setpos( 8, 13 ) ; addstr( k.to_s + " ") ; refresh
  end
ensure
  close_screen
end
