RC_LC_MESSAGES, RC_LC_CTYPE, RC_LC_COLLATE, RC_LC_TIME,
RC_LC_NUMERIC, RC_LC_MONETARY
These variables are passed to the shell without the RC_ prex and represent the
listed categories. The shell proles concerned are listed below. The current setting
can be shown with the command locale.
RC_LC_ALL
This variable, if set, overwrites the values of the variables already mentioned.
RC_LANG
If none of the previous variables are set, this is the fallback. By default, only
RC_LANG is set. This makes it easier for users to enter their own values.
ROOT_USES_LANG
A yes or no variable. If set to no, root always works in the POSIX environment.
The variables can be set with the YaST syscong editor. The value of such a variable
contains the language code, country code, encoding and modier. The individual
components are connected by special characters:
LANG=<language>[[_<COUNTRY>].<Encoding>[@<Modifier>]]
11.4.1 Some Examples
You should always set the language and country codes together. Language settings
follow the standard ISO 639 available at http://www.evertype.com/
standards/iso639/iso639-en.html and http://www.loc.gov/
standards/iso639-2/. Country codes are listed in ISO 3166 available at http://
www.din.de/gremien/nas/nabd/iso3166ma/codlstp1/en_listp1
.html.
It only makes sense to set values for which usable description les can be found in
/usr/lib/locale. Additional description les can be created from the les in
/usr/share/i18n using the command localedef. The description les are part
of the glibc-i18ndata package. A description le for en_US.UTF-8 (for English
and United States) can be created with:
localedef -i en_US -f UTF-8 en_US.UTF-8
