Getting a list of folders in a directory

Question

How do I get a list of the folders that exist in a certain directory with ruby?

Dir.entries() looks close but I don't know how to limit to folders only.

I've found this more useful and easy to use:

Dir.chdir('/destination_directory') Dir.glob('*').select {|f| File.directory? f} 

it gets all folders in the current directory, excluded . and ...

To recurse folders simply use ** in place of *.

The Dir.glob line can also be passed to Dir.chdir as a block:

Dir.chdir('/destination directory') do   Dir.glob('*').select { |f| File.directory? f } end
