Subject: Re: P shows object values, so can u put P and value in txt?

By 'ri p', it was meant that you do that on the command-line.  
(Actually, you'd want to type: 'ri Kernel#p')

'ri' provides documentation for Ruby classes/methods.

If you run the command 'ri Kernel#p', you'll see that 'p' returns nil.  
So you can't use it directly to write to a file. Have you tried 'to_s'?

	f1.puts lines2.diff(lines1).to_s

Offhand, I don't know whether that works or not (don't have diff  
installed at the moment).
