| In Ubuntu, locales are created based on language packs. Proper locale files are generated by ''locale-gen''. Since these files are large, making them persistent is best done by creating a locale extension. | In Ubuntu, locales are created based on language packs.

| Comment out the line in '~/.profile' that hard codes LANG to "en_US.UTF-8": | Either use the //lang// boot code for the desired locale (eg. ''lang=de_CH.UTF-8'' for Swiss German) and comment out the line in '~/.profile' that hard codes LANG to "en_US.UTF-8" ... |

| #LANG=en_US.UTF-8 | #LANG=en_US.UTF-8 |
| </code> | </code> |
| | or change that line to the desired locale directly. |
| |
| Use the //lang// boot code instead for the desired locale (eg. ''lang=de_CH.UTF-8'' for Swiss German). | ==== Fallback Locales ==== |
| | |
| For a first test ''locale'' will complain that it cannot set some LC_ variables but will then list where all but LANGUAGE and LC_ALL are set to the chosen locale code. | |

| =====Generating Locale Files===== | =====Generating Locale Files===== |
| |
| Create a temporary working directory (eg. ~/temp/). | Reboot for the changes to take effect. |
| |
| Create a package list in (eg. ./mylocale.lst) with all desired language choices (eg. English and German): | For a first test ''locale'' will complain that it cannot set some LC_ variables but will then list where all but LANGUAGE and LC_ALL are set to the chosen locale code. |
| | |
| | Create a temporary working directory (eg. ~/temp/). |
| |
| | Create a package list there (eg. ./mylocale-LIST) with all desired language choices (eg. English and German): |
| <code> | <code> |
| ./mylocale.lst: | ./mylocale-LIST: |
| coreutils | coreutils |
| bash | bash |
| </code> | </code> |
| |
| Import the package list using ''sce-import -n -l ./mylocale.lst'' and load them. | Import the package list using ''sce-import -nl ./mylocale-LIST'' and load the extension. Be aware that this may take quite a while. |
| |
| Run ''sudo locale-gen --archive'' (double dash before 'archive') to produce '/usr/lib/locale/locale-archive' containing all locales specified in the language packs. | Run ''sudo locale-gen ''''-''''-''''archive'' to produce '/usr/lib/locale/locale-archive' containing all locales specified in the language packs. Again, this will take a while. |
| | |
| | ===Package Selection=== |
| | |
| | The language packs depend on the //locale// package, which provides the command ''locale-gen''. This is a Bash script which uses the core-utilities plus 'localedef' which is not included in //locale// but rather in //libc-bin//. |
| |
| ===Testing=== | ===Testing=== |
| |
| ''locale'' will show the same list as before without errors. Furthermore ''date +%A'' will print the week-day in the local language. | ''locale'' will show the same list as before without errors. Furthermore ''date +%A'' will print the week-day in the local language. |
