<title>Description</title>
<para>The <filename>/etc/locale.conf</filename> file configures
system-wide locale settings. It is read at early boot by
<citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
<para>The basic file format of <filename>locale.conf</filename> is
a newline-separated list of environment-like shell-compatible
variable assignments. It is possible to source the configuration
from shell scripts, however, beyond mere variable assignments, no
shell features are supported, allowing applications to read the
file without implementing a shell compatible execution
engine.</para>
<para>Note that the kernel command line options
<varname>locale.LANG=</varname>,
<varname>locale.LANGUAGE=</varname>,
<varname>locale.LC_CTYPE=</varname>,
<varname>locale.LC_NUMERIC=</varname>,

<varname>locale.LC_TELEPHONE=</varname>,
<varname>locale.LC_MEASUREMENT=</varname>,
<varname>locale.LC_IDENTIFICATION=</varname> may be
used to override the locale settings at boot.</para>
<para>The locale settings configured in
<filename>/etc/locale.conf</filename> are system-wide and are
inherited by every service or user, unless overridden or unset by
individual programs or individual users.</para>
<para>Depending on the operating system, other configuration files
might be checked for locale configuration as well, however only as
fallback.</para>
<para><filename>/etc/locale.conf</filename> is usually created and updated
using
<citerefentry><refentrytitle>systemd-localed.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
<citerefentry project='man-pages'><refentrytitle>localectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
may be used to alter the settings in this file during runtime from
the command line. Use
<citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
to initialize them on mounted (but not booted) system images.</para>
