Hi All,

Even changing .bash_profile, i am getting only

$

as command prompt.

My bash profile looks like this.

PS1="[\d \t \u@\h:\w ] $ "

stty columns 200
set -o vi

if i run

bash

command and run

PS1="[\d \t \u@\h:\w ] $ "

then it is working as expected.

$ bash
bash-4.1$ PS1="[\d \t \u@\h:\w ] $ "
[Thu Dec 03 01:58:57 tibdata@qabox:~ ] $

Could you please help me how to resolve this issue by putting in .bash_profile?

Hello akshu.agni,

There is a Thumb Rule for editing .profile which is: If we are editing a .profile each time we should log out and login again to server/box, could you please let us know if you have done so.

Thanks,

Yup, done that, but no luck

Hello akshu,

PS1 is usually set in .bashrc , not .bash_profile . .profile type files are for setting environment variables. PS1 is a shell variable, not an environment variable. Chances are, you have a .bashrc that is also setting PS1, could you please try to set it in .bashrc and let me know how it goes.

Thanks,
R. Singh

Hi,

I noticed it was logging into korn shell, that is why .bash_profile wasn't working.

Now new command in .bash_profile is

PS1="${HOSTNAME}:\${PWD##*/} \$ "

Now working as expected.

I will contact my unix team to change default login to bash shell.

Thank you very much for your help.
