Iterate through every file in one directory

Question

How do I write a loop in ruby so that I can execute a block of code on each file?

I\'m new to ruby, and I\'ve concluded that the way to do this is a do each loop.

Answer 1

This is my favorite method for being easy to read:

Dir.glob("*/*.txt") do |my_text_file|
  puts "working on: #{my_text_file}..."
end

And you can even extend this to work on all files in subdirs:

Dir.glob("**/*.txt") do |my_text_file| # note one extra "*"
  puts "working on: #{my_text_file}..."
end
