How to set permissions to directories only in Ubuntu?

Question

ubuntu

Hello dear!
Can you please tell me how to set the rights to a directory and all directories nested in it recursively in Ubuntu, but not touch the files? That is, the usual
chmod -R /
one does not roll, because it also changes to files.

Answer 1

find /path -type d -exec chmod 700 {} \;
-type d - apply to directories only
