Chmod: Change File Permissions Recursively

January 20, 2023 Leave a Comment 
How do you recursively adjust file and directory permissions?

$ find . -type f -exec chmod 644 {} \;
$ find . -type d -exec chmod 755 {} \;
$ chmod 707 images
$ chmod 707 images/stories
$ chown -R daemon:daemon cache
$ chown -R apache:apache cache

Setting permission to 0755 recursive :
$chmod -R 0755 directory_NameHere

To find all files in /home/user/demo directory
$ find /home/user/demo -type f -print

To find all files in /home/user/demo directory with permission 777, enter:
$ find /home/user/demo -type f -perm 777 -print

Apply new permission using the -exec option as follows:
$ find /home/user/demo -type f -perm 777 -print -exec chmod 755 {} \;

To select directories and subdirectories use the following syntax:
$ find /var/www/html -type d -perm 777 -print -exec chmod 755 {} \;
