Subject: Problems moving and renaming pictures with this code, what wrong?

Hi,

I have been reading the book called “Learning to Program” and I have to
say it, for beginners this is a great book, anyways, while practicing
the exercises found in the book I came across this code that for some
reason it doesn’t work.

I have some .jpg pictures located in a folder called “temp-photos” in my
desktop and I want to rename them and then move them to a folder which
is also located in my desktop but in a folder called “my-photos” and I’m
trying the code below but when I run it, it just doesn’t do anything, no
errors but the pictures don’t get moved or renamed.

Any idea what am I doing wrong?  I don’t actually need this program but
since I’m practicing I want to understand what’s going on.

Thanks

Dir.chdir '/Users/userName/Desktop/my-photos'

pic_names = Dir['/Users/userName/Desktop/temp-photos.{JPG,jpg}']

puts 'What would you like to call this batch?'
batch_name = gets.chomp

puts
print "Downloading #{pic_names.length} files: "
pic_number = 1
pic_names.each do |name|
  print '.'
  new_name = if pic_number < 10

  "#{batch_name}0#{pic_number}.jpeg"

else
  "#{batch_name}#{pic_number}.jpeg"

end

File.rename name, new_name

pic_number = pic_number + 1
end
puts
puts 'Done'
