Getting a huge list of files in ruby

Question

I'm trying do some operations on a directory which contains nearly 20 million files, I tried Dir.glob, Dir.foreach and Dir.entries to no success.
Is there anything similar to Csharp's Directory.EnumerateFiles in ruby which can enumerate a huge list of files?

_"... to no success"_ – please be more specific. What happens and how do you use these methods? (i.e. show some code) — Stefan, Oct 04 '16 at 12:10

Dir#read might do the trick.

dir = Dir.new(path)
while entry = dir.read
  puts entry
end

Thanks for your answer, But sadly it didn't do it either. Like other ones I tested, just hangs for a veeery long time and nothing happens. – Jeremy Mc Oct 04 '16 at 10:36
@JeremyMc it's probably working just taking a long time. isn't it printing the entry for you? – Tiago Lopo Oct 04 '16 at 11:24
@Tiago No, It doesn't print anything at all. – Jeremy Mc Oct 04 '16 at 11:29
