How would I do a multiple column sort? I have a file that needs to be sorted by the 3rd column, then 1st, then second. I understand how to do one sort for the csv file but I was unsure of how to do multiple. Also,How would I to do a percentage change between two numbers in a column? Thank you very much. I know these are easy questions but I am still learning how to program in Ruby. -- Posted via http://www.ruby-forum.com/.
