Answer / kiran penujuri

On my machine, the prompt may look like this:
[kiran@54001 kins]$ _

Here "kiran" is my login name, "54001" is the name of the
computer, the second "kins" is the name of my current
working directory, and "_" represents the cursor.

The prompt is set by the environmental variable called
PS1. To display the current setting, I can use:

echo $PS1

The system-wide setting of the prompt (for all users on the
system) is in the file /etc/bashrc which on my system
contains such a line:

PS1="[\u@\h \W]\$ "

To customize the prompt, I can edit the file /etc/bashrc
(as root) and insert almost any text inside the quotation
marks. Here is the meaning of some special codes I may also
choose to use:

\u - username of the current user (= $LOGNAME),
\h - the name of the computer running the shell
(hostname),
\H - entire hostname,
\W - the base of the name of the current working
directory,
\w - the full name of the current working directory,
\$ - display "$" for normal users and "#" for the
root,
\! - history number of the current command,
\# - number of the current command (as executed in the
current shell),
\d - current date,
\t - current time (24-hr),
\T - current time (12-hr) - bash 2.0 only,
\@ - current time (AM/PM format) - bash 2.0 only,
\s - name of the shell,
\a - sound alarm (beep),
\j - number of jobs the user has,
\n - new line,
\\ - backslash,
\[ - begin a sequence of non-printable characters,
\] - end a sequence of non-printable characters,
\nnn - the ASCII character corresponding to the octal
number nnn.
$(date) - output from the date command (or any other
command for that matter),

Here is an example on how to add colour.
PS1="\[\033[1;32m\][\u@\h \W]\$\[\033[0m\] "

You need to have one intiation script in your home
directory for the shell you want to customize. What ever
customization you want to the shell , put those things in
that file. When ever you login to that shell, the
initiation script will execute automatically.
For ex for bash shell the script is .bashrc
