[Linux general] copy diff of 2 folders to a separate folder

[Thomas Kaiser]

Hello All

When I diff to folders, I get a output like this:
Only in /var/www/images/stories/fruit: ABS.jpg

Now, I would like to copy the "Only in" to a different folder (with full 
path name, if possible).

Looks like I am to stupid to find it out by myself (google only shows 
some Windows tools :-) )
