环境

• Red Hat Enterprise Linux 5.5

问题

• Need to validate the locale before adding it into the /etc/sysconfig/i18n file.

• For example the output of locale 'en_US.UTF-8' is 'en_US.utf8'. which is different from actual locale 'en_US.UTF-8'.

决议

• The 'locale -a' command displays all  available locales in the system. So, the values displayed from this  command can be used for LANG parameters in i18n file. If wrong locale is defined in i18n file, it will give following message after  executing 'locale' command (need to logout and login again  after changing LANG value):

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

• The above message says that either locale is not a valid locale or  not installed. Use following command to check the canonical  name:

LC_ALL=[locale name] locale charmap

• For example:

LC_ALL=en_US.UTF-8 locale charmap

• It will give output: UTF-8
