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.

It really isn't the job of diff to do this.

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
