localedef -- define locale environment
localedef [-cDUv] [-f charmap] [-i sourcefile] [-u codeset]
[-w widthfile] localename
The localedef utility converts source definitions for locale categories
into a format usable by the functions and utilities whose operational
behavior is determined by the setting of the locale environment
variables; see environ(7).
The utility reads source definitions for one or more locale categories
belonging to the same locale from the file named in the -i option (if
specified) or from standard input.
Each category source definition is identified by the corresponding
environment variable name and terminated by an END category-name
statement. The following categories are supported:
LC_CTYPE Defines character classification and case conversion.
LC_COLLATE Defines collation rules.
LC_MONETARY Defines the format and symbols used in formatting of
LC_NUMERIC Defines the decimal delimiter, grouping and grouping symbol
for non-monetary numeric editing.
LC_TIME Defines the format and content of date and time information.
LC_MESSAGES Defines the format and values of affirmative and negative
The following options are supported:
-c Creates permanent output even if warning messages have been
-D BSD-style output. Rather than the default of creating the
localename directory and creating files like LC_CTYPE,
LC_COLLATE, etc. in that directory, the output file names have
the format ``<localename>.<category>'' and are dumped to the
Specifies the pathname of a file containing a mapping of
character symbols and collating element symbols to actual
character encodings. This option must be specified if symbolic
names (other than collating symbols defined in a collating-symbol
keyword) are used. If the -f option is not present, the default
character mapping will be used.
The path name of a file containing the source definitions. If
this option is not present, source definitions will be read from
Specifies the name of a codeset used as the target mapping of
character symbols and collating element symbols whose encoding
values are defined in terms of the ISO/IEC 10646-1:2000 standard
position constant values. See NOTES.
-U Ignore the presence of character symbols that have no matching
character definition. This facilitates the use of a common
locale definition file to be used across multiple encodings, even
when some symbols are not present in a given encoding.
-v Emit verbose debugging output on standard output.
The path name of the file containing character screen width
definitions. If not supplied, then default screen widths will be
assumed, which will generally not account for East Asian
encodings requiring more than a single character cell to display,
nor for combining or accent marks that occupy no additional
The following operands are required:
localename Identifies the locale. If the name contains one or more
slash characters, localename will be interpreted as a path
name where the created locale definitions will be stored.
This capability may be restricted to users with appropriate
privileges. (As a consequence of specifying one localename,
although several categories can be processed in one
execution, only categories belonging to the same locale can
localedef creates a directory of files that represents the locale's data,
unless instructed otherwise by the -D (- BSD output) option. The
contants of this directory should generally be copied into the
appropriate subdirectory of /usr/share/locale in order the definitions to
be visible to programs linked with libc.
See environ(7) for definitions of the following environment variables
that affect the execution of localedef: LANG, LC_ALL, LC_COLLATE,
LC_CTYPE, LC_MESSAGES, LC_MONETARY, LC_MUMERIC, LC_TIME, and NLSPATH.
The following exit values are returned:
0 No errors occurred and the locales were successfully created.
1 Warnings occurred and the locales were successfully created.
2 The locale specification exceeded implementation limits or the coded
character set or sets used were not supported by the implementation,
and no locale was created.
>3 Warnings or errors occurred and no output was created.
If an error is detected, no permanent output will be created.
locale(1), iconv_open(3), nl_langinfo(3), strftime(3), environ(7)
If warnings occur, permanent output will be created if the -c option was
specified. The following conditions will cause warning messages to be
o If a symbolic name not found in the charmap file is used for the
descriptions of the LC_CTYPE or LC_COLLATE categories (for other
categories, this will be an error condition).
o If optional keywords not supported by the implementation are present
in the source.
When the -u option is used, the codeset option-argument is interpreted as
a name of a codeset to which the ISO/IEC 10646-1:2000 standard position
constant values are converted. Both the ISO/IEC 10646-1:2000 standard
position constant values and other formats (decimal, hexadecimal, or
octal) are valid as encoding values within the charmap file. The codeset
can be any codeset that is supported by the iconv_open(3) function.
When conflicts occur between the charmap specification of codeset,
mb_cur_max, or mb_cur_min and the corresponding value for the codeset
represented by the -u option-argument codeset, the localedef utility
fails with an error.
When conflicts occur between the charmap encoding values specified for
symbolic names of characters of the portable character set and the
character encoding values defined by the US-ASCII, the result is
localedef first appeared in DragonFly 4.3. It was ported from Illumos
from the point Garrett D'Amore <email@example.com> added multibyte
support (October 2010). John Marino <firstname.lastname@example.org> provided the
alternations necessary to compile cleanly on DragonFly. Baptiste
Daroussin <bapt@FreeBSD.org> converted it to tree(3).
