Compare 2 files and output only the different text.

I know the diff does this but it does output more info than just the different text
(e.g.

$ diff file1 file2
29a30
> /home/alex/Pictures/hello.jpg
1694a1696
> /home/alex/Pictures/hi.jpg

)
How can I make it output only
/home/alex/Pictures/hello.jpg
/home/alex/Pictures/hi.jpg
?
thank you!

diff file1 file2  | egrep '^[<>]' | cut -b 3-

Good, thx for 2nd time
