    Confirmation required before editing sudoers

    I need to enable shutdown and reboot from command without the need of entering sudo password.
    I know i have to edit /etc/sudoers file and add custom entry to it.
    My UserID is already added to admin group.There is this entry for admin group(at the very end of file) already in sudoers file which allows ALL access to admin group.
    So,my question is:if i enter following command AFTER the existing line for %admin
    Code:
    %admin ALL=NOPASSWD: /sbin/shutdown,/sbin/reboot
    will it affect the original rule of %admin?
    My requirement is very clear:sudo pwd to be entered for all sudo commands except shutdown and reboot..
    Waiting for expert's inputs..

    My blog-mate wrote something on this at the very bottom of this post:

    And yeah, it would only exclude the 'admin' group, or even if you want to, a specific user, from entering password for shutdown and reboot. Everything else should still need the 'sudo' password to be entered.

    found another way for achieving what i want.setting uid bit on /sbin/shutdown allows normal users to restart/shutdown from terminal without sudo password.
    Only thing is:it will allow all users and not only the admin group.And that is acceptable at my end.
