ables for the precedence of internationalization variables used
to determine the values of locale categories.)
LC_ALL If set to a non-empty string value, override the values of all
the other internationalization variables.
LC_CTYPE

bytes of text data as characters (for example, single-byte as

and contents of diagnostic messages written to standard error,
and informative messages written to standard output.

Determine the format and contents of the calendar.
NLSPATH
Determine the location of message catalogs for the processing of
LC_MESSAGES .
