locale [option] locale [option] -a locale [option] -m locale [option] name...
When invoked without arguments, locale displays the current locale settings for each locale category (see locale(5)), based on the settings of the environment variables that control the locale (see locale(7)).
If either the -a or the -m option (or one of their long-format equivalents) is specified, the behavior is as follows:
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 example, LC_CTYPE or LC_TIME). For each argument, the following is displayed:
When arguments are supplied, the following options are meaningful:
For a keyword name argument, write the name of the locale category 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.
keyword="value"
The locale command also knows about the following options:
$ 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 environment 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
