locale — get locale-specific (NLS) information
The locale command displays information about the current locale or about available locales.
When invoked without arguments, locale displays the name and actual or implied value of each of the locale-related environment variables in the order shown below, one per line:
LANG LC_CTYPE LC_COLLATE LC_MONETARY LC_NUMERIC LC_TIME LC_MESSAGES LC_ALL
An actual value is the value the variable actually has in the user's environment. An implied value is derived from the value of another variable. Implied values are displayed enclosed in double quotes, while actual values are unquoted.
The determination of implied values is that if the variable LC_ALL is present and has a non-null value, that is the actual value for LC_ALL, and all of the other variables take its value as an implied value. If LC_ALL is not set, all of the LC_* variables that are set are shown with their value as an actual value. Any that have no value are shown with the value of the LANG environment variable as their implied value. LC_ALL is displayed as LC_ALL=\n if it has no value. If LC_ALL is set to NULL or to an invalid string, all of the LC_* variables are set to the default "C" locale.
The value of LC_ALL has precedence over any one of the environment variables LC_* and LANG. If LC_* environment variables are not defined, LANG provides the default. See catopen(3C) for more details.
The locale command can take multiple arguments, which may be locale category names, locale keywords, or the special word charmap (see localedef(1M) for a description of locale keywords and charmaps). If an argument is a keyword, the value associated with that keyword in the current environment is displayed and possibly other information, depending on selected options. If an argument is a category name (i.e., LC_*), the values of all keywords defined in that category are displayed. If an argument is the special word charmap, the charmap file (if any) that was used in the definition of the current locale is displayed.
Non-printable characters are printed as hexadecimal values in the form,
except that if a different escape character has been defined for the locale, it is displayed instead of the "\".
The following options are available:
LANG provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the default value of "C" (see lang(5)) is used. If any of the internationalization variables contains an invalid setting, locale will behave as if all internationalization variables are set to "C". See environ(5).
LC_ALL, when set to a non-empty string value, overrides the values of all other internationalization variables.
LC_CTYPE determines the interpretation of text as single and/or multi-byte characters, the classification of characters as printable, and the characters matched by character class expressions in regular expressions.
LC_MESSAGES determines the locale that should be used to affect the format and content of diagnostic messages written to standard error, and informative messages written to standard output.
NLSPATH determines the location of message catalog for the processing of LC_MESSAGES.
The locale command exits with one of the following values:
If the locale environment variables are set as:
gives the following output:
LANG=fr_FR.iso88591 LC_CTYPE="fr_FR.iso88591" LC_COLLATE=C LC_MONETARY="fr_FR.iso88591" LC_NUMERIC="fr_FR.iso88591" LC_TIME="fr_FR.iso88591" LC_MESSAGES="fr_FR.iso88591" LC_ALL=
LC_ALL=POSIX locale -ck decimal_point
If LANG is set to POSIX and no other locale variables are set, the command:
"." "" ""
which correspond to the keywords decimal_point, thousands_sep, grouping, and alt_digit.
