The -R option in the chmod command stands for "recursive." When you use this option, it applies the specified permission changes to the target directory and all of its contents, including subdirectories and files.
Example Usage
chmod -R 755 /path/to/directoryIn this example, the command sets the permissions of the specified directory and all files and subdirectories within it to 755, which means:
- Owner: read, write, execute
- Group: read, execute
- Others: read, execute
Using -R is useful when you want to change permissions for an entire directory structure without having to specify each file or subdirectory individually.
