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
       initramfs to be rebuilt to take effect during early system boot. The
       initramfs is not rebuilt automatically by localectl.

       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.

       $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.

           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).

       $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.
