locale.conf - Configuration file for locale settings
/etc/locale.conf
The /etc/locale.conf file configures system-wide locale settings. It is read at
early boot by
systemd(1).
The format of locale.conf is a newline-separated list of environment-like
shell-compatible variable assignments, ignoring comments and empty lines. 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. See
os-release(5) for a detailed description of the
format.
Note that the kernel command line options
locale.LANG=,
locale.LANGUAGE=,
locale.LC_CTYPE=,
locale.LC_NUMERIC=,
locale.LC_TIME=,
locale.LC_COLLATE=,
locale.LC_MONETARY=,
locale.LC_MESSAGES=,
locale.LC_PAPER=,
locale.LC_NAME=,
locale.LC_ADDRESS=,
locale.LC_TELEPHONE=,
locale.LC_MEASUREMENT=,
locale.LC_IDENTIFICATION= may be used to
override the locale settings at boot.
The locale settings configured in /etc/locale.conf are system-wide and are
inherited by every service or user, unless overridden or unset by individual
programs or users.
Depending on the operating system, other configuration files might be checked
for locale configuration as well, however only as fallback.
/etc/locale.conf can be updated using
systemd-localed.service(8).
localectl(1) may be used to alter the settings in this file during
runtime from the command line. Use
systemd-firstboot(1) to customize
them on mounted (but not booted) system images.
The following locale settings may be set using /etc/locale.conf:
LANG=,
LANGUAGE=,
LC_CTYPE=,
LC_NUMERIC=,
LC_TIME=,
LC_COLLATE=,
LC_MONETARY=,
LC_MESSAGES=,
LC_PAPER=,
LC_NAME=,
LC_ADDRESS=,
LC_TELEPHONE=,
LC_MEASUREMENT=,
LC_IDENTIFICATION=. Note that
LC_ALL may
not be configured in this file. For details about the meaning and semantics of
these settings, refer to
locale(7).
