How to create temp dir in Ruby?

Question

How do I create a temporary directory in Ruby in a nice way? I would also like to delete it automatically on process exit. Thanks!

Use the Dir.mktmpdir method, from the stdlib:

require 'tmpdir'
Dir.mktmpdir do |d|
  File.open("#{d}/1.txt", 'w') do |f|
    f.write('1.txt') 
  end
end
# at this point 1.txt and the dir no longer exist
