NAME¶
hostnamectl - Control the system hostnameSYNOPSIS¶
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, --helpPrints 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.SEE ALSO¶
