What's the Ruby equivalent of Python's os.walk?

Question

Does anyone know if there\'s an existing module/function inside Ruby to traverse file system directories and files? I\'m looking for something similar to Python\'s os

Answer 1

Find seems pretty simple to me:

require "find"
Find.find('mydir'){|f| puts f}

Answer 2

require 'pathname'

def os_walk(dir)
  root = Pathname(dir)
  files, dirs = [], []
  Pathname(root).find do |path|
    unless path == root
      dirs << path if path.directory?
      files << path if path.file?
    end
  end
  [root, files, dirs]
end

root, files, dirs = os_walk('.')

Answer 3

The following will print all files recursively. Then you can use File.directory? to see if the it is a directory or a file.

Dir['**/*'].each { |f| print f }
