The locale definition file contains all the information that the
localedef(1) command needs to convert it into the binary locale
database.
The definition files consist of sections which each describe a
locale category in detail. See locale(7) for additional details
for these categories.
Syntax
The locale definition file starts with a header that may consist
of the following keywords:
escape_char
is followed by a character that should be used as the
escape-character for the rest of the file to mark
characters that should be interpreted in a special way.
It defaults to the backslash (\).
comment_char
is followed by a character that will be used as the
comment-character for the rest of the file. It defaults
to the number sign (#).
The locale definition has one part for each locale category.
Each part can be copied from another existing locale or can be
defined from scratch. If the category should be copied, the only
valid keyword in the definition is copy followed by the name of
the locale in double quotes which should be copied. The
exceptions for this rule are LC_COLLATE and LC_CTYPE where a copy
statement can be followed by locale-specific rules and selected
overrides.
When defining a locale or a category from scratch, an existing
system- provided locale definition file should be used as a
reference to follow common glibc conventions.
Locale category sections
The following category sections are defined by POSIX:
* LC_CTYPE
* LC_COLLATE
* LC_MESSAGES
* LC_MONETARY
* LC_NUMERIC
* LC_TIME
In addition, since version 2.2, the GNU C library supports the
following nonstandard categories:
* LC_ADDRESS
* LC_IDENTIFICATION
* LC_MEASUREMENT
* LC_NAME
* LC_PAPER
* LC_TELEPHONE
See locale(7) for a more detailed description of each category.
