As far as I know 'diff' doesn't support that functionality. You should look at the 'sdiff' program. It will show differences side by side and effectively shows the lines that are the same. > Would it be easily (enough) to add that functionality to diff?

If the files are sorted the 'comm' program is designed to do this. There are a number of tools that will show the differences between two files side by side. Here are a few. emacs-emerge meld mgdiff sdiff tkdiff xxdiff Bob
