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.

I have a few questions to ask and would appreciate all relevant input. This might be easy for some but can somebody help answer some of these;
1. Write a shell script that takes three numbers as arguments and outputs to the screen the sum of these numbers.
2. Write a shell script that reads three numbers and outputs to the screen the sum of these numbers.
3. Write a shell script that takes three numbers as arguments and outputs to the screen the maximum of these numbers.
4. Write a shell script that takes three numbers as arguments and outputs to the screen the three numbers in sorted order. You are not allowed to use the "internal built-in sort function".
5. Suppose the file employee.txt contains the following lines:
100 Thomas Manager Sales $5,000 Auckland
200 Jason Developer Technology $5,500 Auckland
300 Sanjay Sysadmin Technology $7,000 Hamilton
400 Nisha Manager Marketing $9,500 Hamilton
500 Randy DBA Technology $6,000 Hamilton
a. Write an awk that prints the second and the last element in each line.
