Supposing you're reading from stdin or from files passed as argument and you're writing to stdout: ARGF.each { |line| puts line.split.join(', ') } If you want to output to file output_file = open ('output.cvs', 'w') ARGF.each { |line| output_file.puts line.split.join(', ') } [a beginner in Ruby] -- Posted via http://www.ruby-forum.com/.
