localeのマニュアル

LOCALE(1)                      Linux User Manual                     LOCALE(1)

NAME
       locale - get locale-specific information

SYNOPSIS
       locale [option]
       locale [option] -a
       locale [option] -m
       locale [option] name...

DESCRIPTION
       The  locale  command  displays information about the current locale, or
       all locales, on standard output.

       When invoked without arguments, locale displays the current locale set‐
       tings  for  each locale category (see locale(5)), based on the settings
       of the environment variables that control the locale  (see  locale(7)).
       Values  for variables set in the environment are printed without double
       quotes, implied values are printed with double quotes.

       If either the -a or the -m option (or one of their long-format  equiva‐
       lents) is specified, the behavior is as follows:

       -a, --all-locales
              Display  a  list of all available locales.  The -v option causes
              the LC_IDENTIFICATION metadata about each locale to be  included
              in the output.

       -m, --charmaps
              Display   the  available  charmaps  (character  set  description
              files).  To display the current character set  for  the  locale,
              use locale -c charmap.

       The  locale  command  can  also be provided with one or more arguments,
       which are the names of locale keywords (for example,  date_fmt,  ctype-
       class-names, yesexpr, or decimal_point) or locale categories (for exam‐
       ple, LC_CTYPE or LC_TIME).  For each argument, the  following  is  dis‐
       played:

       *  For a locale keyword, the value of that keyword to be displayed.

       *  For  a  locale category, the values of all keywords in that category
          are displayed.

       When arguments are supplied, the following options are meaningful:

       -c, --category-name
              For a category name argument, write the name of the locale cate‐
              gory on a separate line preceding the list of keyword values for
              that category.

              For a keyword name argument, write the name of the locale  cate‐
              gory  for  this keyword on a separate line preceding the keyword
              value.

              This option improves readability when  multiple  name  arguments
              are specified.  It can be combined with the -k option.

       -k, --keyword-name
              For  each  keyword  whose value is being displayed, include also
              the name of that keyword, so that the output has the format:

                  keyword="value"

       The locale command also knows about the following options:

       -v, --verbose
              Display additional information for some command-line option  and
              argument combinations.

       -?, --help
              Display  a  summary  of  command-line  options and arguments and
              exit.

       --usage
              Display a short usage message and exit.

       -V, --version
              Display the program version and exit.

FILES
       /usr/lib/locale/locale-archive
              Usual default locale archive location.

       /usr/share/i18n/locales
              Usual default path for locale definition files.

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008.

EXAMPLE
       $ locale
       LANG=en_US.UTF-8
       LC_CTYPE="en_US.UTF-8"
       LC_NUMERIC="en_US.UTF-8"
       LC_TIME="en_US.UTF-8"
       LC_COLLATE="en_US.UTF-8"
       LC_MONETARY="en_US.UTF-8"
       LC_MESSAGES="en_US.UTF-8"
       LC_PAPER="en_US.UTF-8"
       LC_NAME="en_US.UTF-8"
       LC_ADDRESS="en_US.UTF-8"
       LC_TELEPHONE="en_US.UTF-8"
       LC_MEASUREMENT="en_US.UTF-8"
       LC_IDENTIFICATION="en_US.UTF-8"
       LC_ALL=

       $ locale date_fmt
       %a %b %e %H:%M:%S %Z %Y

       $ locale -k date_fmt
       date_fmt="%a %b %e %H:%M:%S %Z %Y"

       $ locale -ck date_fmt
       LC_TIME
       date_fmt="%a %b %e %H:%M:%S %Z %Y"

       $ locale LC_TELEPHONE
       +%c (%a) %l
       (%a) %l
       11
       1
       UTF-8

       $ locale -k LC_TELEPHONE
       tel_int_fmt="+%c (%a) %l"
       tel_dom_fmt="(%a) %l"
       int_select="11"
       int_prefix="1"
       telephone-codeset="UTF-8"

       The following example compiles a custom locale from the ./wrk directory
       with  the  localedef(1) utility under the $HOME/.locale directory, then
       tests the result with the date(1) command, and then sets  the  environ‐
       ment  variables  LOCPATH and LANG in the shell profile file so that the
       custom locale will be used in the subsequent user sessions:

       $ mkdir -p $HOME/.locale
       $ I18NPATH=./wrk/ localedef -f UTF-8 -i fi_SE $HOME/.locale/fi_SE.UTF-8
       $ LOCPATH=$HOME/.locale LC_ALL=fi_SE.UTF-8 date
       $ echo "export LOCPATH=\$HOME/.locale" >> $HOME/.bashrc
       $ echo "export LANG=fi_SE.UTF-8" >> $HOME/.bashrc
