I’m learning to use Linux with Opensuse IDE version 13.1.
I wonder if it is possible to merge the commands rm -r with diff - r?
Goal
Remove the files 1.txt,2.txt,2.txt of path1, because it does not possess in the path2.

Direct use of the command rsync, example:
To use the path2 as "model":
rsync -r --delete path2/ path1
Important: The bar / is important to copy the contents of the directory and the directory itself.

I believe you can use the command xargs. Take a look at the manual for details.
It would be something like (not exactly):
diff -r path1 path2 | xargs rm
The exit of diff has a few more words than not the file names (Only in path1:, for example), then you may need to deal with a regular expression.
