yn, a simple yes/no helper script

#!/usr/bin/env ruby

response = nil

begin
  while !%w[y n].include?(response) do
    print "y/n? "
    response = gets.chomp
    puts "response: #{(response).inspect}"
  end

  if response == "y"
    exit 0
  else
    exit 1
  end
rescue Interrupt
  exit 2
end

This is just a short script I wrote to ask whether something did or didn’t happen correctly. Just answer y or n. It’s sometimes very useful when an automated test is infeasible for git-bisect.
