Creating a custom bash prompt

Here is an easy tip for those who like to customize the bash prompt of his server.

Scenario:
-----------
The bash prompt of my server looks as below, with name "localhost"











I don't like to see localhost on my server, I want it to be customized with my name.

So, here is an easy step:

Create a file named "/etc/profile.d/custom_prompt.sh".

Enter the below content to the file:
----
export PS1='[root@MANINMANOJ]#'
-----

Now, the file looks as below snippet:
------
[root@MANINMANOJ]#cat /etc/profile.d/custom_prompt.sh
export PS1='[root@MANINMANOJ]#'

------

Execute the script using sh:

------

sh /etc/profile.d/custom_prompt.sh

------

Now, logout and login again to the shell.  

You will see that the bash prompt changed.
