NAME

       hostnamectl - Control the system hostname

SYNOPSIS

       hostnamectl [OPTIONS...] {COMMAND}

DESCRIPTION

       hostnamectl may be used to query and change the system hostname and related settings.

       This tool distinguishes three different host names: the high-level "pretty" hostname which might include
       all kinds of special characters (e.g. "Lennart's Laptop"), the static hostname which is used to
       initialize the kernel hostname at boot (e.g. "lennarts-laptop"), and the transient hostname which might
       be assigned temporarily due to network configuration and might revert back to the static hostname if
       network connectivity is lost and is only temporarily written to the kernel hostname (e.g. "dhcp-47-11").

       Note that the pretty hostname has little restrictions on the characters used, while the static and
       transient hostnames are limited to the usually accepted characters of internet domain names.

       The static host name is stored in /etc/hostname, see hostname(5) for more information. The pretty host
       name, chassis type and icon name are stored in /etc/machine-info, see machine-id(5).

OPTIONS

       The following options are understood:

       -h, --help
           Prints a short help text and exits.

       --version
           Prints a short version string and exits.

       --no-ask-password
           Don't query the user for authentication for privileged operations.

       -H, --host
           Execute the operation remotely. Specify a hostname, or username and hostname separated by @, to
           connect to. This will use SSH to talk to a remote system.

       --static, --transient, --pretty
           If set-hostname is invoked and one or more of these options are passed only the selected hostnames is
           updated.

       The following commands are understood:

       status
           Show current system hostname and related information.

       set-hostname [NAME]
           Set the system hostname. By default this will alter the pretty, the static, and the transient
           hostname alike, however if one or more of --static, --transient, --pretty are used only the selected
           hostnames are changed. If the pretty hostname is being set, and static or transient are being set as
           well the specified host name will be simplified in regards to the character set used before the
           latter are updated. This is done by replacing spaces by "-" and removing special characters. This
           ensures that the pretty and the static hostname are always closely related while still following the
           validity rules of the specific name. This simplification of the hostname string is not done if only
           the transient and/or static host names are set, and the pretty host name is left untouched. Pass the
           empty string "" as hostname to reset the selected hostnames to their default (usually "localhost").

       set-icon-name [NAME]
           Set the system icon name. The icon name is used by some graphical applications to visualize this
           host. The icon name should follow the Icon Naming Specification[1]. Pass an empty string to this
           operation to reset the icon name to the default value which is determined from chassis type (see
           below) and possibly other parameters.

       set-chassis [TYPE]
           Set the chassis type. The chassis type is used by some graphical applications to visualize the host
           or alter user interaction. Currently, the following chassis types are defined: desktop, laptop,
           server, tablet, handset, as well as the special chassis types vm and container for virtualized
           systems that lack an immediate physical chassis. Pass an empty string to this operation to reset the
           chassis type to the default value which is determined from the firmware and possibly other
           parameters.

EXIT STATUS

       On success 0 is returned, a non-zero failure code otherwise.
