What is the best way to write to a file in Ruby? [closed]

Question

I would like to write some data to a file in Ruby. What is the best way to do that?

Answer 1

File.open("a_file", "w") do |f|
    f.write "some data"
end

You can also use f << "some data" or f.puts "some data" according to personal taste/necessity to have newlines. Change the "w" to "a" if you want to append to the file instead of truncating with each open.
