Changing default language on RHEL 4 Device

I was testing a application  on RHEL 4 device. There was one set of test cases to be executed in different locale. Searching in google how to change the default language of machine. After lots of googling, i found, it was in bits and pieces. So I taught to share this information the tested version of it.

While installing RHEL 4, usually we install default lanaguage as English. If you want to change to other locale its very simple in RHEL 4, you just need to change only one file with proper local.

Default configuration would be :
[root@rhel4-device ~]# cat /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SUPPORTED="en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"
[root@rhel4-device ~]#

If you want to change the locale to french, you need to change the LANG and remove the rest.
[root@rhel4-device ~]# cat /etc/sysconfig/i18n
LANG="fr_FR.UTF-8"
[root@rhel4-device ~]#reboot
