therefore, edit your .bash_profile to call .bashrc and you will always execute .bashrc from any "style" of login.

I checked .bash_profile it is not set.
this is my .bash_profile

...........................................................................
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH
unset USERNAME
.............................................................................

still i have the same prompt

does not exists.

Try putting the PS1=... at the end of your .bashrc script?

Thanks to all of u.

i commented few lines in bashrc now i am getting my desired prompt.

----------------------------------------------------------------------------------------------------
#if [ -f /etc/bashrc ]; then
# . /etc/bashrc
#fi
#if [ -f /etc/bash.bashrc ]; then
# . /etc/bash.bashrc
#fi
----------------------------------------------------------------------------------------------------

But still i have a question

What is the need of bashrc in /etc/ ?
means what is the role ?

you are using the file /etc/.bashrc not the one in your home as the ~/.bashrc is saying

and I asked you if /etc/.bashrc is exist or not and I didn't get the answer yet
(kindly note the "." before the word bashrc)

your ~/.bashrc is excuting the code /etc/.bashrc when you login.(not good)

when your ~/.bashrc is removed you need to modify your ".bash.profile" in a way that is to use the /etc/.bashrc when you lose your ~/.bashrc (somehow) kindly see below:-

add this condition to your .bashrc.profile and remove it from your ~/.bashrc:-

if [ -f $HOME/.bashrc ]; then
 . $HOME/.bashrc
else
. /etc/.bashrc
fi

I made modifications in my .bash_profile.
