Privileged commands without sudo

Motive: Bring out some specific commands like shutdown, restart from sudo restriction.

Example: #sudo reboot to #reboot

For changing this, we need to edit /etc/sudoers.tmp file for that we need to run the following command on the terminal[Applications->Accessories->Terminal].

#sudo visudo

A file will open in your default text editor [nano is my default]

Then add user list just after the line says: '# User alias specification', like this:

User_Alias USERS = thecoderin,ubutrix,user3

And add those commands for avoid sudo prefix just after '# Cmnd alias specification', like this:

Cmnd_Alias SHUTDOWN_CMDS = /sbin/shutdown, /sbin/reboot, /sbin/halt

Then We need to give the permissions to the USERS to run SHUTDOWN_CMDS without sudo and passwords. Goto end after the %admin line put this line

USERS ALL=(ALL) NOPASSWD: SHUTDOWN_CMDS
