Get names of all files from a folder with Ruby

Question

I want to get all file names from a folder using Ruby.

Answer 1

If you want get an array of filenames including symlinks, use

Dir.new('/path/to/dir').entries.reject { |f| File.directory? f }

or even

Dir.new('/path/to/dir').reject { |f| File.directory? f }

and if you want to go without symlinks, use

Dir.new('/path/to/dir').select { |f| File.file? f }

As shown in other answers, use Dir.glob('/path/to/dir/**/*') instead of Dir.new('/path/to/dir') if you want to get all the files recursively.
