Linux: Set permission only to directories

Question

I have to change the permissions of the htdocs directory in apache to a certain group and with certain read/write/execute.

The directories need to have 775

Answer 1

Use find's -type option to limit actions to files and directories. Use the -o option to specify alternate actions for different types, so you only have to run find once, rather than separately for each type.

find htdocs -type f -exec chmod 664 {} + -o -type d -exec chmod 775 {} +
