Easiest way is to open a file for writing and with a block write the contents to it.

File.open("test_file.txt", "a+") do |file| #opens the file "test_file.txt" in append mode, if it does not exist it creates it.
    file.puts "Hello world"
end #closes the file for you

Otherway is to use File.new but that forces you to ensure to close the file etc.
