6 localectl - Control the system locale and keyboard layout settings
7
9 localectl [OPTIONS...] {COMMAND}
10
12 localectl may be used to query and change the system locale and
13 keyboard layout settings. It communicates with systemd-localed(8) to
14 modify files such as /etc/locale.conf and /etc/vconsole.conf.
15 The system locale controls the language settings of system services and
17 of the UI before the user logs in, such as the display manager, as well
18 as the default for users after login.
19 The keyboard settings control the keyboard layout used on the text
21 console and of the graphical UI before the user logs in, such as the
22 display manager, as well as the default for users after login.
23 Note that the changes performed using this tool might require the
25 initramfs to be rebuilt to take effect during early system boot. The
26 initramfs is not rebuilt automatically by localectl.
27 Note that systemd-firstboot(1) may be used to initialize the system
29 locale for mounted (but not booted) system images.
30
32 The following commands are understood:
33 status
35 Show current settings of the system locale and keyboard mapping. If
36 no command is specified, this is the implied default.
37 set-locale LOCALE, set-locale VARIABLE=LOCALE...
39 Set the system locale. This takes one locale such as "en_US.UTF-8",
40 or takes one or more locale assignments such as "LANG=de_DE.utf8",
41 "LC_MESSAGES=en_GB.utf8", and so on. If one locale without variable
42 name is provided, then "LANG=" locale variable will be set. See
43 locale(7) for details on the available settings and their meanings.
44 Use list-locales for a list of available locales (see below).
45 list-locales
47 List available locales useful for configuration with set-locale.
48 set-keymap MAP [TOGGLEMAP]
50 Set the system keyboard mapping for the console and X11. This takes
51 a mapping name (such as "de" or "us"), and possibly a second one to
52 define a toggle keyboard mapping. Unless --no-convert is passed,
53 the selected setting is also applied as the default system keyboard
54 mapping of X11, after converting it to the closest matching X11
55 keyboard mapping. Use list-keymaps for a list of available keyboard
56 mappings (see below).
57 list-keymaps
59 List available keyboard mappings for the console, useful for
60 configuration with set-keymap.
61 set-x11-keymap LAYOUT [MODEL [VARIANT [OPTIONS]]]
63 Set the system default keyboard mapping for X11 and the virtual
64 console. This takes a keyboard mapping name (such as "de" or "us"),
65 and possibly a model, variant, and options, see kbd(4) for details.
66 Unless --no-convert is passed, the selected setting is also applied
67 as the system console keyboard mapping, after converting it to the
68 closest matching console keyboard mapping.
69 list-x11-keymap-models, list-x11-keymap-layouts,
71 list-x11-keymap-variants [LAYOUT], list-x11-keymap-options
72 List available X11 keymap models, layouts, variants and options,
73 useful for configuration with set-keymap. The command
74 list-x11-keymap-variants optionally takes a layout parameter to
75 limit the output to the variants suitable for the specific layout.
76
78 The following options are understood:
79 --no-ask-password
81 Do not query the user for authentication for privileged operations.
82 --no-convert
84 If set-keymap or set-x11-keymap is invoked and this option is
85 passed, then the keymap will not be converted from the console to
86 X11, or X11 to console, respectively.
87 -H, --host=
89 Execute the operation remotely. Specify a hostname, or a username
90 and hostname separated by "@", to connect to. The hostname may
91 optionally be suffixed by a port ssh is listening on, separated by
92 ":", and then a container name, separated by "/", which connects
93 directly to a specific container on the specified host. This will
94 use SSH to talk to the remote machine manager instance. Container
95 names may be enumerated with machinectl -H HOST. Put IPv6 addresses
96 in brackets.
97 -M, --machine=
99 Execute operation on a local container. Specify a container name to
100 connect to, optionally prefixed by a user name to connect as and a
101 separating "@" character. If the special string ".host" is used in
102 place of the container name, a connection to the local system is
103 made (which is useful to connect to a specific user's user bus:
104 "--user --machine=lennart@.host"). If the "@" syntax is not used,
105 the connection is made as root user. If the "@" syntax is used
106 either the left hand side or the right hand side may be omitted
107 (but not both) in which case the local user name and ".host" are
108 implied.
109 -h, --help
111 Print a short help text and exit.
112 --version
114 Print a short version string and exit.
115 --no-pager
117 Do not pipe output into a pager.
118
120 On success, 0 is returned, a non-zero failure code otherwise.
121
123 $SYSTEMD_LOG_LEVEL
124 The maximum log level of emitted messages (messages with a higher
125 log level, i.e. less important ones, will be suppressed). Either
126 one of (in order of decreasing importance) emerg, alert, crit, err,
127 warning, notice, info, debug, or an integer in the range 0...7. See
128 syslog(3) for more information.
129 $SYSTEMD_LOG_COLOR
131 A boolean. If true, messages written to the tty will be colored
132 according to priority.
133 This setting is only useful when messages are written directly to
135 the terminal, because journalctl(1) and other tools that display
136 logs will color messages based on the log level on their own.
137 $SYSTEMD_LOG_TIME
139 A boolean. If true, log messages will be prefixed with a timestamp.
140 This setting is only useful when messages are written directly to
142 the terminal or a file, because journalctl(1) and other tools that
143 display logs will attach timestamps based on the entry metadata on
144 their own.
145 $SYSTEMD_LOG_LOCATION
147 A boolean. If true, messages will be prefixed with a filename and
148 line number in the source code where the message originates.
149 Note that the log location is often attached as metadata to journal
151 entries anyway. Including it directly in the message text can
152 nevertheless be convenient when debugging programs.
153 $SYSTEMD_LOG_TID
155 A boolean. If true, messages will be prefixed with the current
156 numerical thread ID (TID).
157 Note that the this information is attached as metadata to journal
159 entries anyway. Including it directly in the message text can
160 nevertheless be convenient when debugging programs.
161 $SYSTEMD_LOG_TARGET
163 The destination for log messages. One of console (log to the
164 attached tty), console-prefixed (log to the attached tty but with
165 prefixes encoding the log level and "facility", see syslog(3), kmsg
166 (log to the kernel circular log buffer), journal (log to the
167 journal), journal-or-kmsg (log to the journal if available, and to
168 kmsg otherwise), auto (determine the appropriate log target
169 automatically, the default), null (disable log output).
170 $SYSTEMD_PAGER
172 Pager to use when --no-pager is not given; overrides $PAGER. If
173 neither $SYSTEMD_PAGER nor $PAGER are set, a set of well-known
174 pager implementations are tried in turn, including less(1) and
175 more(1), until one is found. If no pager implementation is
176 discovered no pager is invoked. Setting this environment variable
177 to an empty string or the value "cat" is equivalent to passing
178 --no-pager.
179 $SYSTEMD_LESS
181 Override the options passed to less (by default "FRSXMK").
182 Users might want to change two options in particular:
184 K
186 This option instructs the pager to exit immediately when Ctrl+C
187 is pressed. To allow less to handle Ctrl+C itself to switch
188 back to the pager command prompt, unset this option.
189 If the value of $SYSTEMD_LESS does not include "K", and the
191 pager that is invoked is less, Ctrl+C will be ignored by the
192 executable, and needs to be handled by the pager.
193 X
195 This option instructs the pager to not send termcap
196 initialization and deinitialization strings to the terminal. It
197 is set by default to allow command output to remain visible in
198 the terminal even after the pager exits. Nevertheless, this
199 prevents some pager functionality from working, in particular
200 paged output cannot be scrolled with the mouse.
201 See less(1) for more discussion.
203 $SYSTEMD_LESSCHARSET
205 Override the charset passed to less (by default "utf-8", if the
206 invoking terminal is determined to be UTF-8 compatible).
207 $SYSTEMD_PAGERSECURE
209 Takes a boolean argument. When true, the "secure" mode of the pager
210 is enabled; if false, disabled. If $SYSTEMD_PAGERSECURE is not set
211 at all, secure mode is enabled if the effective UID is not the same
212 as the owner of the login session, see geteuid(2) and
213 sd_pid_get_owner_uid(3). In secure mode, LESSSECURE=1 will be set
214 when invoking the pager, and the pager shall disable commands that
215 open or create new files or start new subprocesses. When
216 $SYSTEMD_PAGERSECURE is not set at all, pagers which are not known
217 to implement secure mode will not be used. (Currently only less(1)
218 implements secure mode.)
219 Note: when commands are invoked with elevated privileges, for
221 example under sudo(8) or pkexec(1), care must be taken to ensure
222 that unintended interactive features are not enabled. "Secure" mode
223 for the pager may be enabled automatically as describe above.
224 Setting SYSTEMD_PAGERSECURE=0 or not removing it from the inherited
225 environment allows the user to invoke arbitrary commands. Note that
226 if the $SYSTEMD_PAGER or $PAGER variables are to be honoured,
227 $SYSTEMD_PAGERSECURE must be set too. It might be reasonable to
228 completely disable the pager using --no-pager instead.
229 $SYSTEMD_COLORS
231 Takes a boolean argument. When true, systemd and related utilities
232 will use colors in their output, otherwise the output will be
233 monochrome. Additionally, the variable can take one of the
234 following special values: "16", "256" to restrict the use of colors
235 to the base 16 or 256 ANSI colors, respectively. This can be
236 specified to override the automatic decision based on $TERM and
237 what the console is connected to.
238 $SYSTEMD_URLIFY
240 The value must be a boolean. Controls whether clickable links
241 should be generated in the output for terminal emulators supporting
242 this. This can be specified to override the decision that systemd
243 makes based on $TERM and other conditions.
