Does Ruby have mkdir -p? [duplicate]

How to create directories recursively in ruby?

In Ruby, how could I do:

mkdir -p cool/beans

Here's what I came up with:

Dir.mkdir('cool') unless File.directory?('cool')
cool_beans_path = File.join('cool', 'beans')
Dir.mkdir(cool_beans_path) unless File.directory?(cool_beans_path)

But, isn't there a better way?

I know I could do:
```
system('mkdir', '-p', File.join('cool', 'beans'))
```
But, that's not platform independent, is it? Like, it works on Mac but not on Windows, right?

require 'fileutils'
FileUtils.mkdir_p 'cool/beans'
