locale - get locale-specific information
locale [-a | -m]
locale [-ck] name...
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
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 fol-
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.
The following options are supported:
-a Writes information about all available public locales.
The available locales include POSIX, representing the
-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
-m Writes names of available charmaps; see localedef(1).
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.
Example 1: Examples of the locale utility
In the following examples, the assumption is that locale
environment variables are set as follows:
The command locale would result in the following output:
LC_ALL=POSIX locale -ck 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\
affirmative processing goes here
non-affirmative processing goes here
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
The following exit values are returned:
0 All the requested information was found and output
>0 An error occurred.

If LC_CTYPE or keywords in the category LC_CTYPE are speci-
fied, only the values in the range 0x00-0x7f are written
If LC_COLLATE or keywords in the category LC_COLLATE are
specified, no actual values are written out.
