Rsync how to include directories but not files?

Question

I have a directory structure and files like this

data/
data/a.txt
data/folder/
data/folder/b.txt
data/folder/folder/
data/folder/folder/c.txt
...
         


        

Answer 1

$ rsync -a -f"+ */" -f"- *" source/ destination/

"The two -f arguments mean, respectively, "copy all directories" and then "do not copy anything else"."
