Counter

$stdout.sync = true
20.times do |_counter|
  counter = _counter.to_s
  print counter + "\b" * counter.size
  sleep 1
end

FYI: puts and p both add "\n" to the output if it is not yet there.

Pretty new to ruby (and programming but am getting better).

I am importing data with DBI and I want display and counter as each
row is imported. I can get the display to show:

1
2
3
4
5
6
7
8
9
10
etc...

but I don't want a linebreak after the counter is displayed. I want it
just to keep refreshing itself, basically. Am I missing something
with puts or print or p? Any ideas?

printf doesn't
