Touches all linked files if not exist, use Capistrano 3.4.0

deploy.rb

### part of config/deploy.rb
namespace :deploy do
  namespace :check do
    # desc 'Touches all linked files'
    task :touch_all_linked_files do
      on release_roles :all do
        fetch(:linked_files, []).each do |file|
          target = shared_path.join(file)
          unless File.file?(target)
            info "File.file?('#{target}') : #{File.file?(target)}"
            execute :touch, target
            info "Touched : #{target}"
          end
        end
      end
    end
  end
  before 'deploy:check:linked_files', 'deploy:check:touch_all_linked_files'
end

File.file?() is running at local, not remote, so always get false.
need change to above:
unless test("[ -f #{target} ]")
end
