File and folder permissions Linux

You can execute the following commands to modify file/folder permissions and ownership on Linux:

Change permissions
chmod
Change ownership
chown
Imagine a folder called *Books* on the Desktop to which you wanted to give full read/write access to, you could execute the following command in the terminal:

sudo chmod -R ugo+rw ~/Desktop/Books

Defining the above command :
- **sudo** – used to gain admin rights. - **chmod** – the command to modify permissions - **-R** – this modifies the permission of the parent folder and the child objects within - **ugo+rw** – this gives User, Group, and Other read and write access.
