The locale.alias database file (/etc/locale.alias) is used by the
locale
command and the
X Window System
It describes aliases for the locales, with each line being of the
form
<alias> <localename>
Where <localename> is in the POSIX format: xx_YY.CHARSET.
The first two letters xx are the ISO-639 Language code,
the next two YY are the ISO-3166 Country code,
and the Charset is one of the character sets (listed in
/usr/share/i18n/charsets
).
The aliases can be free text; they are normally the English language
name, or simpler versions of the POSIX locale name.
Lines beginning with Hash ("#") are treated as comments and ignored.
