Quickstart

Intro

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.

Options

  • -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.

Bash Env Vars

  • LANG Used to determine the locale category for any category not specifically selected with a variable starting with LC_.
  • LC_ALL This variable overrides the value of LANG and any other LC_ variable specifying a locale category.
  • LC_COLLATE This variable determines the collation order used when sorting the results of pathname expansion, and determines the behavior of range expressions, equivalence classes, and collating sequences within pathname expansion and pattern matching.
  • LC_CTYPE This variable determines the interpretation of characters and the behavior of character classes within pathname expansion and pattern matching.
  • LC_MESSAGES This variable determines the locale used to translate double-quoted strings preceded by a $.
  • LC_NUMERIC This variable determines the locale category used for number formatting.

Usage

Default

When invoked without arguments, locale displays the current locale settings for each locale category, based on the settings of the environment variables that control the locale.
