I'm sorry I don't quite understand what you're asking. Does your script need to ask for a user name? Please clarify...

So you're wanting to authenticate with the users login and pass that's on the machine they're running it from? Why? Why not just make sure they are a certain user like:

Code:
[`whoami` = "root" ] && echo "I am root"
[`whoami` = "shiv2001in" ] && echo "I am unix.com user shiv2001in"

In other words, your script can test to see who the user is. You can say:
Code:
[ ! `whoami` = "user1" -o "user2" -o "user" ] && echo "You are not authorized to run this script"

because I want only certain users in the admin group to run - once they supply their real/won password the script should continue else should exit out.

Yea see I personally wouldn't want to be "logging in" to your script with my username and password. Leaves a lot to be desired as far as security. If you allow the user to login to the shell, and then test to make sure the user is in fact "user1" "user2" "user" etc, you can make the script exit if they are not on the list.

correct - but, in my case we have lots of admins and I want to allow certain admins only - $who -m|awk '{print $1}' <- if they are these admins only I will allow - becase whoami says root and many admins can sudo to root and they can become root and I do not want those admins or all admins to run this script and want only those who are in my admin group to run this. Hope I'm not making too complicate.

Code:
[ ! `whoami` = "user1" -o "user2" -o "user" ] && echo "You are not authorized to run this script"

This says if you're NOT user1 or user2 or user to echo "You are not authorized to run this script" which can be followed by && exit 1 to make it exit the script immediately if they are not one of those users

Code:
[ ! `whoami` = "user1" -o "user2" -o "user" ] && echo "You are not authorized to run this script" && exit 1

If your setup has `whoami` use it instead of going through `who -m | awk '{print $1}'` does the same thing. Save yourself some typing...
