How to change all file permissions to 644 and all folder permissions to 755 recursively using chmod in the following two situation:
- If they had
777permissions - Regardless of the permission (with ANY permissions)
find . -type d -perm 777 -exec chmod 755 {} \; (for changing the directory permission)
find . -type f -perm 777 -exec chmod 644 {} \; (for changing the file permission)
If they did not have 777 permissions, we easily remove the -perm 777 part.
Regardless of the permissions:
chmod -R a=r,a+X,u+w /your/path

according to man chmod: The letters rwxXst select file mode bits for the affected users: read (r), write (w), execute (or search for directories) (x), execute/search only if the file is a directory or already has execute permission for some user (X) ... – mrossi Jun 19 '17 at 13:44

Excellent! This inspired a one liner to reset permissions to umask
chmod -R "$(umask -S | sed 's/x/X/g')" /your/path– Steven Shaw Jan 30 at 22:50
sudo find /path/to/someDirectory -type f -print0 | xargs -0 sudo chmod 644
and
sudo find /path/to/someDirectory -type d -print0 | xargs -0 sudo chmod 755
