Loop through files in a directory

I know this is a nub question, but the documentation on ruby is
terrible.

How do I loop through all of the files in a directory?

Thanks for your help.

harp:~ > ls dir
a b c


harp:~ > cat a.rb
class Dir
def self.ls dir, glob = File.join('**', '**'), &block
ret = [] unless block
Dir.glob(File.join(dir, glob)) do |entry|
block ? block.call(entry) : ret.push(entry)
end
ret
end
end

Dir.ls 'dir' do |entry|
puts entry
end

entries = Dir.ls 'dir'
p entries


harp:~ > ruby a.rb
dir/a
dir/b
dir/c
["dir/a", "dir/b", "dir/c"]
