runner.rb

RAILS RUNNER APPLICATION IN 10 STEPS !!!
1.- rails runner -d mysql
2.- cd runner
3.- Edit config/database.yml
4.- rake db:create
5.- ./script/generate scaffold Md5 password:string md5hash:string
6.- rake db:migrate
7.- irb DEMO

    puts "Hello World"

8.- ruby ./script/console development;
    Md5.find(:all)
    i=Md5.new({:password=>"from_console1",:md5hash=>"console_hash1"})
    i.save
    Md5.create({:password=>"from_console2",:md5hash=>"console_hash2"})

9.- ruby ./script/runner -e development 'Md5.create({:password=>"from_runner",:md5hash=>"runner_hash"})'

10.- Lets play with Ruby Code:

a)
require 'digest/md5'
md5_test = Digest::MD5.hexdigest("abc")
puts md5_test

b)
abcd=("a".."z").to_a
num=(0..9).to_a

@abc=abcd+num

@abc.each do |a|
  puts a
end

c)
require 'digest/md5'
abcd=("a".."z").to_a
num=(0..9).to_a
@abc=abcd+num

@abc.each do |a|
md5_a = Digest::MD5.hexdigest("#{a}")
my_runner = "ruby ./script/runner -e development 'Md5.create({:password=>\"#{a}\",:md5hash=>\"#{md5_a}\"})'"
puts my_runner
%x(#{my_runner})
end

d)
abcd=("a".."z").to_a
num=(0..9).to_a
@abc=abcd+num

@abc.each do |a|
  @abc.each do |b|
    @abc.each do |c|

          my_extension = "com"
          my_domain = "www.#{a}#{b}#{c}.#{my_extension}"
          my_command = "dig +short #{my_domain}"
          puts my_command

    end
  end
end
