locale locale_name |
You can use locale with both the initial installation and upgrade options.
locale designates the locale packages you want to install (or to add when upgrading) for the specified locale_name. The locale_name values are the same as those used for the $LANG environment variable. Appendix B, Locale Values contains a list of valid locale values.
If you have preconfigured a default locale, it is automatically installed. The English language packages are installed by default.
You can specify a locale keyword for each locale you need to add to a system.
