Note: If you change your hostname using the hostnamectl command, no system reboot is required during the process.

Step 4:

After that we need to edit the / etc / hosts file to make changes by entering the following command:

$ sudo to edit /Etc/Host.

Apply the hostnamectl command so that you can confirm your hostname change to ensure that the changes are reflected in the system.
