    The hostnamectl Command 

    hostnamectl command provides a proper API used to control Linux system hostname and change its related settings. The command also helps to change the hostname without actually locating and editing the /etc/hostname file on a given system.

    Syntax:

    hostnamectl [ OPTIONS ] COMMAND ....

    Where COMMAND can be any of the following:

    • status: Used to check current hostname settings.
    • set-hostname NAME: Used to set system hostname.
    • set-icon-name NAME: Used to set icon name for host.
    • set-chassis NAME: Set chassis type for host.

    Types of hostname:

    • Static: Assigned by system admin and it is used to initialize the kernel hostname during boot time.
    • Dynamic or Transient: Assigned by mDNS server or DHCP server during run time.
    • Pretty: A high-level hostname assigned by system admin or end-user.

    Command Options:

    Option Meaning
    --no-ask-password Do not query the user for authentication for privileged operations.
    -H, --host= Execute the operation remotely. Specify a hostname, or a username and hostname separated by "@", to connect to. The hostname may optionally be suffixed by a port ssh is listening on, separated by ":", and then a container name, separated by "/", which connects directly to a specific container on the specified host.
    -M, --machine= Execute operation on a local container. Specify a container name to connect to, optionally prefixed by a user name to connect as and a separating "@" character. If the special string ".host" is used in place of the container name, a connection to the local system is made
