Hi Gaurav,
There is only bash.bashrc exists, I have never did anything to this file before. As below:
# /etc/bash.bashrc for SuSE Linux
#
# PLEASE DO NOT CHANGE /etc/bash.bashrc There are chances that your changes
# will be lost during system upgrades. Instead use /etc/bash.bashrc.local
# for your local settings, favourite global aliases, VISUAL and EDITOR
# variables, etc ...
#
# Check which shell is reading this file
#
