This is a very good example where other people's specialties can greatly help. jmcnamara's experience with cvs diff totally nullified my snippet. I don't care my XP point, I want to openly accept the fact that I was so wrong, and didn't realize cvs diff's full functionality.

THANK YOU VERY MUCH, I FEEL SO GRATEFUL.

UPDATE

After tried --suppress-common-lines for a while, I went back to my snippet again.

The problem with that option is that, it only shows you the differences, with no indication of their positions in the source file, which make me totally lost. I don't just want to know how big the difference is, I want to know exactly where those modifications are.

One great benefit I got from my snippet is that, it extracts the real differences, and at the same time, it gives me the line numbers of those real differences (not in the source files, but in the result file from cvs diff, but it is still good enough, as the result from cvs diff without --supress-common-lines does contain copies of source files), so I can easily locate them in the source code.

However I still love the --suppress-common-lines option, and will use it in the future, whenever it fits. Thank you jmcnamara.
