i had a challenge today, i need to change mi images files to 644 but not my directories, so i was wondering how do i do this. its simple with this command

find . -type f -print0 | xargs -0 chmod 644

basically all its doing its looking for all the files (-f) and the output of that is to change the permissions to 644

simple right

how about only to directories?
find . -type d -print0 | xargs -0 chmod 644

see the difference?
