How to create directories recursively in ruby?

Question

I want to store a file as /a/b/c/d.txt, but I do not know if any of these directories exist and need to recursively create them if necessary. How can one do this in ruby?

Answer 1

You could also use your own logic

def self.create_dir_if_not_exists(path)
  recursive = path.split('/')
  directory = ''
  recursive.each do |sub_directory|
    directory += sub_directory + '/'
    Dir.mkdir(directory) unless (File.directory? directory)
  end
end

So if path is 'tmp/a/b/c' if 'tmp' doesn't exist 'tmp' gets created, then 'tmp/a/' and so on and so forth.
