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

This is what works for me:

Dir.entries(dir).select { |f| File.file?(File.join(dir, f)) }

Dir.entries returns an array of strings. Then, we have to provide a full path of the file to File.file?, unless dir is equal to our current working directory. That's why this File.join().
