localedef - compile locale definition files
localedef [options] outputpath
localedef --list-archive [options]
localedef --delete-from-archive [options] localename ...
localedef --add-to-archive [options] compiledpath
The localedef program reads the indicated charmap and input files, com-
piles them to a binary form quickly usable by the locale functions in
the C library (setlocale(3), localeconv(3), etc.), and places the out-
put in outputpath.
The outputpath argument is interpreted as follows:
* If outputpath contains a slash character ('/'), it is interpreted as
the name of the directory where the output definitions are to be
stored. In this case, there is a separate output file for each lo-
cale category (LC_TIME, LC_NUMERIC, and so on).
* If the --no-archive option is used, outputpath is the name of a sub-
directory in /usr/lib/locale where per-category compiled files are
* Otherwise, outputpath is the name of a locale and the compiled lo-
cale data is added to the archive file /usr/lib/locale/locale-ar-
chive. A locale archive is a memory-mapped file which contains all
the system-provided locales; it is used by all localized programs
when the environment variable LOCPATH is not set.
In any case, localedef aborts if the directory in which it tries to
write locale files has not already been created.
If no charmapfile is given, the value ANSI_X3.4-1968 (for ASCII) is
used by default. If no inputfile is given, or if it is given as a dash
(-), localedef reads from standard input.
A few options direct localedef to do something other than compile lo-
cale definitions. Only one of these options should be used at a time.
Delete the named locales from the locale archive file.
List the locales contained in the locale archive file.
Add the compiledpath directories to the locale archive file.
The directories should have been created by previous runs of lo-
caledef, using --no-archive.
Some of the following options are sensible only for certain operations;
generally, it should be self-evident which ones.
-f charmapfile, --charmap=charmapfile
Specify the file that defines the character set that is used by
the input file. If charmapfile contains a slash character
('/'), it is interpreted as the name of the character map. Oth-
erwise, the file is sought in the current directory and the de-
fault directory for character maps. If the environment variable
I18NPATH is set, $I18NPATH/charmaps/ and $I18NPATH/ are also
searched after the current directory. The default directory for
character maps is printed by localedef --help.
-i inputfile, --inputfile=inputfile
Specify the locale definition file to compile. The file is
sought in the current directory and the default directory for
locale definition files. If the environment variable I18NPATH
is set, $I18NPATH/locales/ and $I18NPATH are also searched after
the current directory. The default directory for locale defini-
tion files is printed by localedef --help.
-u repertoirefile, --repertoire-map=repertoirefile
Read mappings from symbolic names to Unicode code points from
repertoirefile. If repertoirefile contains a slash character
('/'), it is interpreted as the pathname of the repertoire map.
Otherwise, the file is sought in the current directory and the
default directory for repertoire maps. If the environment vari-
able I18NPATH is set, $I18NPATH/repertoiremaps/ and $I18NPATH
are also searched after the current directory. The default di-
rectory for repertoire maps is printed by localedef --help.
-A aliasfile, --alias-file=aliasfile
Use aliasfile to look up aliases for locale names. There is no
default aliases file.
Set the prefix to be prepended to the full archive pathname. By
default, the prefix is empty. Setting the prefix to foo, the
archive would be placed in foo/usr/lib/locale/locale-archive.

Conform strictly to POSIX. Implies --verbose. This option cur-
rently has no other effect. POSIX conformance is assumed if the
environment variable POSIXLY_CORRECT is set.

tion, if the locale is in the archive file already, an error oc-
Do not use the locale archive file, instead create outputpath as
a subdirectory in the same directory as the locale archive file,
and create separate output files for locale categories in it.
This is helpful to prevent system locale archive updates from
overwriting custom locales created with localedef.
Print a usage summary and exit. Also prints the default paths
used by localedef.
Print a short usage summary and exit.
Print the version number, license, and disclaimer of warranty
One of the following exit values can be returned by localedef:
0 Command completed successfully.
1 Warnings or errors occurred, output files were written.
4 Errors encountered, no output created.
The --posix flag is assumed if this environment variable is set.
A colon-separated list of search directories for files.
Usual default character map path.
Usual default path for locale definition files.
Usual default repertoire map path.
Usual default locale archive location.
Usual default path for compiled individual locale data files.

dresses and geography-related items.

Compile the locale files for Finnish in the UTF-8 character set and add
it to the default locale archive with the name fi_FI.UTF-8:
localedef -f UTF-8 -i fi_FI fi_FI.UTF-8
The next example does the same thing, but generates files into the
fi_FI.UTF-8 directory which can then be used by programs when the envi-
ronment variable LOCPATH is set to the current directory (note that the
last argument must contain a slash):
localedef -f UTF-8 -i fi_FI ./fi_FI.UTF-8
