    Execute the following command using a terminal:

    sudo sed -i 's/present-host-name/new-host-name/' /etc/hosts
sudo sed -i 's/present-host-name/new-host-name/' /etc/hostname

    You can check your present-host-name by cat /etc/hostname or hostname.

    Then reboot the computer, to see the changes.

    • Open a terminal and issue the command

      gksu gedit /etc/hosts

    • Then change the line 

      127.0.1.1   victor-System-Product-Name

      with

       127.0.1.1    your-desired-name

    • Then also open the file /etc/hostname with command gksu gedit /etc/hostname and change the hostname there to reflect the new name.

    • Then reboot the computer, to see the changes

  3. You can use the built in service hostnamectl

    sudo hostnamectl set-hostname [NEW-HOSTNAME]

    replacing [NEW-HOSTNAME] with the hostname you would like this should work immediately on most things but I would reboot for good measure.

  4. Since there are plenty of ways to get something done here is one more:

    While in your root directory: 

    cd /etc
sudo vi hostname

    Type in your admin password, press Enter.

    Press i to 'insert' and change existing device name to the desired device name.

    Press Esc and type :wq!, press Enter.

    Restart the system for the change to take affect.
