Subject: Re: compare 2 text files - check for difference - Please help

require 'diff/lcs/Array'

file = File.open("1.txt",'r')
 @row = {}
    file.each_line do |@line|
      key, val = @line.chomp.split(",",0)
      @row[key] = val
  end

 file2 = File.open("2.txt",'r')
 @row2 = {}
    file2.each_line do |@line2|
      key2, val2 = @line2.chomp.split(",",0)
      @row2[key2] = val2
  end


puts diffs = Diff::LCS.diff(@line,@line2)

testing files contents...
1.txt  2.txt
1,2    1,2,3

outputed when files different as above:
#<Diff::LCS::Change:0x2e5d95c>
#<Diff::LCS::Change:0x2e5da60>
#<Diff::LCS::Change:0x2e5d90c>

outputed when files are identicial
#<Diff::LCS::Change:0x2e5da88>

I want to be able to say that 2.txt contained '3' therefore the file was 
not the same on that line. Thanks. MC
