Environment Variables

Internationalization Variables

There are no additional semantics for the following environment variables:

• LC_COLLATE
• LC_CTYPE
• LC_MESSAGES
• LC_MONETARY
• LC_NUMERIC
• LC_TIME

The default locale is the POSIX locale.

There are no additional criteria for determining valid locales.
