File writing

Hi, I know you can write to a file using 'w', but this erases all the
previous data. How can I add new items to an existing document without
losing the data?

Thanks!

Use "a" instead of "w". That will Append new data to the end of the
file.

filename = File.open("test","a") do |f|
f.puts "append to file";
f.close();
end
