Which is more idiomatic ruby?

test.rb

path = '/home/you/foo/bar/baz'
# assume this path has a folder called hello and a file within the hello folder

Dir[File.join(path, '**', '*')].each do |file| 
	puts file.split(path)
	# => hello/world.rb
end

# vs.

Dir[File.join(path, '**', '*')].each do |file| 
	puts file.sub(path, '')
	# => hello/world.rb
end
