Linux How to Change Hostname
Hostname identifies a computer on the network and it is visible in the terminal. We set up hostname during the installation operating system, but sometimes we want to change it.
Use command “hostname” to change hostname:
hostname new_hostname
Will set the hostname of the system to new_hostname. Open a new terminal to verify change hostname.
If you want to change the hostname permanent use the command “sysctl kernel.hostname” to change it:
sysctl kernel.hostname=NewHostname
Output: kernel.hostname = Newhostname
Command hostname without any parameter prints the current hostname of the system.
