LOCALECTL(1) localectl LOCALECTL(1)
NAME
localectl - Control the system locale and keyboard layout settings
SYNOPSIS
localectl [OPTIONS...] {COMMAND}
DESCRIPTION
localectl may be used to query and change the system locale and
keyboard layout settings. It communicates with systemd-localed(8) to
modify files such as /etc/locale.conf and /etc/vconsole.conf.
The system locale controls the language settings of system services and
of the UI before the user logs in, such as the display manager, as well
as the default for users after login.
The keyboard settings control the keyboard layout used on the text
console and of the graphical UI before the user logs in, such as the
display manager, as well as the default for users after login.
Note that the changes performed using this tool might require the
initrd to be rebuilt to take effect during early system boot. The
initrd is not rebuilt automatically by localectl, this task has to be
performed manually, usually using a tool like dracut(8).
Note that systemd-firstboot(1) may be used to initialize the system
locale for mounted (but not booted) system images.
COMMANDS
The following commands are understood:
status
Show current settings of the system locale and keyboard mapping. If
no command is specified, this is the implied default.
set-locale LOCALE, set-locale VARIABLE=LOCALE...
Set the system locale. This takes one locale such as "en_US.UTF-8",
or takes one or more locale assignments such as "LANG=de_DE.utf8",
"LC_MESSAGES=en_GB.utf8", and so on. If one locale without variable
name is provided, then "LANG=" locale variable will be set. See
locale(7) for details on the available settings and their meanings.
Use list-locales for a list of available locales (see below).
list-locales
List available locales useful for configuration with set-locale.
set-keymap MAP [TOGGLEMAP]
Set the system keyboard mapping for the console and X11. This takes
a mapping name (such as "de" or "us"), and possibly a second one to
define a toggle keyboard mapping. Unless --no-convert is passed,
the selected setting is also applied as the default system keyboard
mapping of X11, after converting it to the closest matching X11
keyboard mapping. Use list-keymaps for a list of available keyboard
mappings (see below).
list-keymaps
List available keyboard mappings for the console, useful for
configuration with set-keymap.
set-x11-keymap LAYOUT [MODEL [VARIANT [OPTIONS]]]
Set the system default keyboard mapping for X11 and the virtual
console. This takes a keyboard mapping name (such as "de" or "us"),
and possibly a model, variant, and options, see kbd(4) for details.
Unless --no-convert is passed, the selected setting is also applied
as the system console keyboard mapping, after converting it to the
closest matching console keyboard mapping.
list-x11-keymap-models, list-x11-keymap-layouts,
list-x11-keymap-variants [LAYOUT], list-x11-keymap-options
List available X11 keymap models, layouts, variants and options,
useful for configuration with set-keymap. The command
list-x11-keymap-variants optionally takes a layout parameter to
limit the output to the variants suitable for the specific layout.
OPTIONS
The following options are understood:
--no-ask-password
Do not query the user for authentication for privileged operations.
--no-convert
If set-keymap or set-x11-keymap is invoked and this option is
passed, then the keymap will not be converted from the console to
X11, or X11 to console, respectively.
-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. This will
use SSH to talk to the remote machine manager instance. Container
names may be enumerated with machinectl -H HOST. Put IPv6 addresses
in brackets.
-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 (which is useful to connect to a specific user's user bus:
"--user --machine=lennart@.host"). If the "@" syntax is not used,
the connection is made as root user. If the "@" syntax is used
either the left hand side or the right hand side may be omitted
(but not both) in which case the local user name and ".host" are
implied.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
--no-pager
Do not pipe output into a pager.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
ENVIRONMENT
$SYSTEMD_LOG_LEVEL
The maximum log level of emitted messages (messages with a higher
log level, i.e. less important ones, will be suppressed). Either
one of (in order of decreasing importance) emerg, alert, crit, err,
warning, notice, info, debug, or an integer in the range 0...7. See
syslog(3) for more information.
$SYSTEMD_LOG_COLOR
A boolean. If true, messages written to the tty will be colored
according to priority.
This setting is only useful when messages are written directly to
the terminal, because journalctl(1) and other tools that display
logs will color messages based on the log level on their own.
$SYSTEMD_LOG_TIME
A boolean. If true, console log messages will be prefixed with a
timestamp.
This setting is only useful when messages are written directly to
the terminal or a file, because journalctl(1) and other tools that
display logs will attach timestamps based on the entry metadata on
their own.
$SYSTEMD_LOG_LOCATION
A boolean. If true, messages will be prefixed with a filename and
line number in the source code where the message originates.
Note that the log location is often attached as metadata to journal
entries anyway. Including it directly in the message text can
nevertheless be convenient when debugging programs.
$SYSTEMD_LOG_TID
A boolean. If true, messages will be prefixed with the current
numerical thread ID (TID).
Note that the this information is attached as metadata to journal
entries anyway. Including it directly in the message text can
nevertheless be convenient when debugging programs.
$SYSTEMD_LOG_TARGET
The destination for log messages. One of console (log to the
attached tty), console-prefixed (log to the attached tty but with
prefixes encoding the log level and "facility", see syslog(3), kmsg
(log to the kernel circular log buffer), journal (log to the
journal), journal-or-kmsg (log to the journal if available, and to
kmsg otherwise), auto (determine the appropriate log target
automatically, the default), null (disable log output).
$SYSTEMD_PAGER
Pager to use when --no-pager is not given; overrides $PAGER. If
neither $SYSTEMD_PAGER nor $PAGER are set, a set of well-known
pager implementations are tried in turn, including less(1) and
more(1), until one is found. If no pager implementation is
discovered no pager is invoked. Setting this environment variable
to an empty string or the value "cat" is equivalent to passing
--no-pager.
Note: if $SYSTEMD_PAGERSECURE is not set, $SYSTEMD_PAGER (as well
as $PAGER) will be silently ignored.
$SYSTEMD_LESS
Override the options passed to less (by default "FRSXMK").
Users might want to change two options in particular:
K
This option instructs the pager to exit immediately when Ctrl+C
is pressed. To allow less to handle Ctrl+C itself to switch
back to the pager command prompt, unset this option.
If the value of $SYSTEMD_LESS does not include "K", and the
pager that is invoked is less, Ctrl+C will be ignored by the
executable, and needs to be handled by the pager.
X
This option instructs the pager to not send termcap
initialization and deinitialization strings to the terminal. It
is set by default to allow command output to remain visible in
the terminal even after the pager exits. Nevertheless, this
prevents some pager functionality from working, in particular
paged output cannot be scrolled with the mouse.
Note that setting the regular $LESS environment variable has no
effect for less invocations by systemd tools.
See less(1) for more discussion.
$SYSTEMD_LESSCHARSET
Override the charset passed to less (by default "utf-8", if the
invoking terminal is determined to be UTF-8 compatible).
Note that setting the regular $LESSCHARSET environment variable has
no effect for less invocations by systemd tools.
$SYSTEMD_PAGERSECURE
Takes a boolean argument. When true, the "secure" mode of the pager
is enabled; if false, disabled. If $SYSTEMD_PAGERSECURE is not set
at all, secure mode is enabled if the effective UID is not the same
as the owner of the login session, see geteuid(2) and
sd_pid_get_owner_uid(3). In secure mode, LESSSECURE=1 will be set
when invoking the pager, and the pager shall disable commands that
open or create new files or start new subprocesses. When
$SYSTEMD_PAGERSECURE is not set at all, pagers which are not known
to implement secure mode will not be used. (Currently only less(1)
implements secure mode.)
Note: when commands are invoked with elevated privileges, for
example under sudo(8) or pkexec(1), care must be taken to ensure
that unintended interactive features are not enabled. "Secure" mode
for the pager may be enabled automatically as describe above.
Setting SYSTEMD_PAGERSECURE=0 or not removing it from the inherited
environment allows the user to invoke arbitrary commands. Note that
if the $SYSTEMD_PAGER or $PAGER variables are to be honoured,
$SYSTEMD_PAGERSECURE must be set too. It might be reasonable to
completely disable the pager using --no-pager instead.
$SYSTEMD_COLORS
Takes a boolean argument. When true, systemd and related utilities
will use colors in their output, otherwise the output will be
monochrome. Additionally, the variable can take one of the
following special values: "16", "256" to restrict the use of colors
to the base 16 or 256 ANSI colors, respectively. This can be
specified to override the automatic decision based on $TERM and
what the console is connected to.
$SYSTEMD_URLIFY
The value must be a boolean. Controls whether clickable links
should be generated in the output for terminal emulators supporting
this. This can be specified to override the decision that systemd
makes based on $TERM and other conditions.
