How to change your hostname in Ubuntu without restarting

Posted on March 11, 2013 by Ahmed Tawfik
  • Replace your old hostname in the /etc/hostname file with the new one: “sudo vi /etc/hostname”
  • Replace your old hostname beside the 127.0.0.1 in the /etc/hosts file
  • Run the following “sudo service hostname start”
  • Exit the terminal and open a new one, you’ll find the new hostname applied

    Or just use this command after you changed the name in /etc/hostname

    hostname -F /etc/hostname and the hostname will be changed
