Some shell's problem

[James Ng Yuen Sum <james_nghk_debian_user@yahoo.com.hk>]

Hi,

I am a chinese user. If i want to use xcin(one input chinese characters
XIM server), I need to open a konsole and type the following command:

export LANG=zh_TW.Big5
env|grep LC

I have tried to add the above command in ~./bashrc and ~/.profile, but
when i start kde again, i have to type again, so that i want to ask
which file i need to edit so that the above two commands can run
automatically when i start linux.

Regards,
James Ng
