Here’s a cool little script that will recursively chmod, giving a permission based on whether it’s dealing with a file or a directory. This is very convenient when you want to add that +x to directories but not files.
find $1 -type f -exec chmod $2 {} ;
find $1 -type d -exec chmod $3 {} ;
Go ahead and edit /usr/bin/chmod_script, copy paste these 2 lines in there, then issue a chmod 755 /usr/bin/chmod_script as root, that’s it!
Usage syntax is as follows:
chmod_script <directory_to_start_the_recursion_in> <permissions_for_files> <permissions_for+directories>
so if I want to use it on /var/www do:
chmod_script /var/www 644 755
Enjoy!
