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

To get all files (strictly files only) recursively:

Dir.glob('path/**/*').select { |e| File.file? e }

Or anything that's not a directory (File.file? would reject non-regular files):

Dir.glob('path/**/*').reject { |e| File.directory? e }

Alternative Solution

Using Find#find over a pattern-based lookup method like Dir.glob is actually better. See this answer to "One-liner to Recursively List Directories in Ruby?".
