Subject: "unless" with Regex

I have a series of folders in a directory that I am trying to read out
of...I want to do a regex that ignores anything EXCEPT 4 digit numbers
(as in a proper year)...I tried using the "unless" option but doesnt
seem to be working:

unless !/\d{4}/


Here is the code-snippet

Dir.foreach("/Volumes/gac_repo/video") do |year|
  #unless the folder name isnt a 4 digit number...
  unless !/\d{4}/
    #print the name of the folder which hopefully should just be years
    puts "The folder name is: #{year}"
    #Do stuff to the files inside of the folders
    Dir.foreach("/Volumes/gac_repo/video/#{year}") do |name|
     puts "The file name is #{name}"
  end
    end
end
