If you have a reasonable normal shell you could do this: spinners = ['|', '/', '-', '\\'] printf "%s", spinners[0] STDOUT.flush 1.upto(1000) do |i| printf "\b%s", spinners[i % spinners.size] STDOUT.flush sleep(0.1) end Works on OSX's bash anyway... I'm sure someone out there can condense that into one line :) Replace the sleep() call with something that takes awhile to process otherwise all you see is a blur. -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
