How to give permission to all files in a directory using chmod in Linux?

You can use the chmod command to grant permissions to all files in the directory.

To grant rwxr-xr-x permissions to all files in the directory /path/to/directory and its subdirectories, you can use the following command:

chmod -R 755 /path/to/directory

The -R parameter indicates recursively changing the permissions of all files in the directory and its subdirectories.755 means giving the directory owner read, write, and execute permissions, while giving other users only read and execute permissions.

To grant different permissions to all files in the directory, simply replace 755 with the appropriate permission numbers.
