How can I get a gameobject with an attached component ?

What should : print(gameObject.name); mean ?

I don't understand your question. What is the problem?

The page explains that you can access the gameObject that the component is attached to.

i cant understand this. how can i get the gameobject from the component. In my situation the character controller.

You need to write a script with a reference to the Character Controller:

     public CharacterController cc;
 
     void Start() {
         cc.gameObject.name = "new name";
     }

if the script is already on the same gameObject that has the Character Controller, then you can simply:

     void Start() {
         gameObject.name = "new name";
     }

Thank you but can I also write : public CharacterController cc; public GameObject player;

      void  Start () {
            player = cc.gameObject ;
       }
