Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Depending on your distro, there will be different ways around that. Most involve booting from the rescue disc or USB-stick that you have handy and fixing sudoers. When editing that file, it is a good idea to use the program "visudo" instead of directly working on it. You can still lock yourself out while using "visudo" but at least it will not be because of a syntax errror as it prevents those.
If you had used visudo to edit the /etc/sudoers file it would have prompted you if you made any errors before you could exit out of it. This way is alot more safer cus in case you made a mistake you will know beforehand, and be able fix it before it becomes an issue.
