I'm talking about removing the line terminators. It looks like the OP is trying to compare unchomped records from a Windows text file with the same from a Unix text file. The comparison is failing because although the text is the same the line terminators are different. It now looks like he's trimming trailing whitespace from only the Windows files so they still don't match.
