You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: unlink.rb
    path of file: ./repos/brew/Library/Homebrew/cmd
    
    the code of the file until where you have to start completion: #:  * `unlink` [`--dry-run`] <formu
    
  def unlink
    unlink_args.parse

    raise KegUnspecifiedError if args.remaining.empty?

    mode = OpenStruct.new
    mode.dry_run = true if args.dry_run?

    ARGV.kegs.each do |keg|
      if mode.dry_run
        puts "Would remove:"
        keg.unlink(mode)
        next
      end

      keg.lock do
        print "Unlinking #{keg}... "
        puts if args.verbose?
        puts "#{keg.unlink(mode)} symlinks removed"
      end
    end
