The default prompt will be
root@monu dev]#
Can we change the "root@monu" part and give it a desired name?

This is changed by changing the environment variable PS1.
You can see the current value of PS1 by:
root@monu dev# echo $PS1
You can see the value to be equal to \u@\h \w\$, where:
\u: username\h: hostname\w: current working directory\$: a#symbol for the root user, a$symbol for other users
If you want the change to be permanent, you have to add the script changing the value of PS1 in ~/.bashrc, since that it gets executed every time a user logs in.

1Don't forget to put it into your ~/.bashrc file also. e.g. `PS1="myname \\$ "'.– KeithApr 5, 2012 at 6:55

5~/.bashrc is not executed every time a user logs in. “When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists.” – man bash /INVOCATION Apr 5, 2012 at 7:39

This depends on your shell. As an important side note, you should never use the root account as a personal account. Create a normal user and set up access to sudo. Please check your distribution manual as to how to do this.
In zsh, you need to set the PROMPT variable like so:
PROMPT='%{ESC[38;5;24m%};%{ESC[0m%} '
zshell offers a lot of other options and this is really a minimal prompt.
In bash, you can set it this way:
local ROOK="\[\033[38;5;24m\]"
local DEFAULT="\[\033[0;39m\]"
PS1="${ROOK}\$${DEFAULT} "
Note that in both cases, I have a 256 colour enabled terminal. The man page will help a lot (man bash or man zsh).

2Here, you stated the root account case correctly, IMO - it is not to be used as a personal account (except on some very low-footprint embedded systems). Apr 5, 2012 at 8:46
