Your primary prompt is configured via the PS1 environment variable. You could insert this in his ~/.bashrc file

Code:
export PS1='[\u:\W]\$ '
which will result in something like this:

Code:
[username:directory]$ yada yada
then you can add this to his ~/.bash_profile:

Code:
[[ -f ~/.bashrc ]] && . ~/.bashrc
When this user logs in, or when you su - to him, he'll have the same prompt.

More about the special characters to configure your prompt

It may be the compiled-in value for bash to use when PS1 is not set or it may be set in the system-wide bash initialisation files such as /etc/profile

i noticed that when PS1 is set to [\u@\h \W]\$ , and i'm in the home directory it displays the home directory e.g. [root@PHOENIX u05]#,
if i go to a subdirectory cd /u05/oradata, the display looks like [root@PHOENIX oradata]# , i've been playing with the different values for PS1
but i can't seem to find one that would display [root@PHOENIX u05/oradata]#.... is this possible ?

Yes it's possible. Maybe by \w instead of \W

Have a look at the link I posted before. It's a nice and short wiki about the bash prompt and special characters like \W, \w etc.

Cheers
