Linux command line…How do I change from $ to #?

Question

I'm working with a sed editor and I realize that the command prompt is:

[darkchild@localhost ~]$

How can I change the above command so that it ends in 

For example:

[darkchild@localhost ~]#

My friend suggested me to write this command

#!/bin/bash

But it does not change the prompt too.

Answer 1

Canonically # means root shell. As per my knowledge, you probably need not to this because it would confuse other users of your system. If you don't want to do this, you can edit the PROMPT variable.
