Source Give users specific access with sudo
If you're new to Linux chances are you know about Ubuntu. Ubuntu has done a great job making a distribution of Linux new-user friendly. One of the ways they have done this is by making the root user (the super user) somewhat transparent. The user can not log in as the root user in a Ubuntu system (unless they have made it so) and the user has to use the sudo utility in order to run administrative tasks.
Now as an administrator of a Linux system, the sudo utility is a great way to manage user permissions with regards to access (especially with regard to applications). Say, for example, you have a specific executable file placed in /usr/sbin that you want your standard users to be able to use along with the ability to use the tools in the whole /usr/bin. Or say you have one specific user on your system that you want to give full administrative access to. This can all be done with the help of sudo. Let's see how.
