NAME


locale - get locale-specific information

SYNOPSIS


locale [-a | -m]


locale [-ck] name...


DESCRIPTION


The locale utility writes information about the current locale
environment, or all public locales, to the standard output. For the
purposes of this section, a public locale is one provided by the
implementation that is accessible to the application.


When locale is invoked without any arguments, it summarizes the current
locale environment for each locale category as determined by the settings
of the environment variables.


When invoked with operands, it writes values that have been assigned to
the keywords in the locale categories, as follows:

o Specifying a keyword name selects the named keyword and the
category containing that keyword.

o Specifying a category name selects the named category and all
keywords in that category.

OPTIONS


The following options are supported:

-a
Writes information about all available public locales. The
available locales include POSIX, representing the POSIX locale.


-c
Writes the names of selected locale categories. The -c option
increases readability when more than one category is selected (for
example, via more than one keyword name or via a category name). It
is valid both with and without the -k option.


-k
Writes the names and values of selected keywords. The
implementation may omit values for some keywords; see OPERANDS.


-m
Writes names of available charmaps; see localedef(1).


OPERANDS


The following operand is supported:

name
The name of a locale category, the name of a keyword in a locale
category, or the reserved name charmap. The named category or
keyword will be selected for output. If a single name represents
both a locale category name and a keyword name in the current
locale, the results are unspecified; otherwise, both category and
keyword names can be specified as name operands, in any sequence.


EXAMPLES


Example 1: Examples of the locale utility




In the following examples, the assumption is that locale environment
variables are set as follows:


LANG=locale_x LC_COLLATE=locale_y


The command locale would result in the following output:


LANG=locale_x
LC_CTYPE="locale_x"
LC_NUMERIC="locale_x"
LC_TIME="locale_x"
LC_COLLATE=locale_y
LC_MONETARY="locale_x"
LC_MESSAGES="locale_x"
LC_ALL=


The command


LC_ALL=POSIX locale -ck decimal_point


would produce:


LC_NUMERIC
decimal_point="."


The following command shows an application of locale to determine whether
a user-supplied response is affirmative:


if printf "%s\n" "$response" | /usr/xpg4/bin/grep -Eq\
"$(locale yesexpr)"
then
affirmative processing goes here
else
non-affirmative processing goes here
fi


ENVIRONMENT VARIABLES


See environ(5) for the descriptions of LANG, LC_ALL, LC_CTYPE,
LC_MESSAGES, and NLSPATH.


The LANG, LC_*, and NLSPATH environment variables must specify the
current locale environment to be written out. These environment variables
will be used if the -a option is not specified.

EXIT STATUS


The following exit values are returned:

0
All the requested information was found and output successfully.


>0
An error occurred.

NOTES


If LC_CTYPE or keywords in the category LC_CTYPE are specified, only the
values in the range 0x00-0x7f are written out.


If LC_COLLATE or keywords in the category LC_COLLATE are specified, no
actual values are written out.
