Slide 1: Introduction	Hello and welcome to the spoken tutorial on Overview of Linux AWK commands.
Slide 2: Learning Objectives	In this tutorial we will learn about Linux AWK and The tutorials covered in the Linux AWK series
Slide 3: System requirement	To record this tutorial, I am using Ubuntu Linux 16.04 OS
Slide 3: AWK	*AWK is a used for searching and extracting data from a file. We can also manipulate the data and generate reports using AWK.
Slide 4: AWK	Like any programming language, AWK also has Variables Operators Conditional Statements Loops Single and Multi Dimensional Arrays Built-in Functions and User Defined functions
Slide 5: AWK Process	During the search process- A file will be treated as a sequence of records. Each line will be considered as a single record with multiple fields. Then AWK searches for the given pattern. And performs the desired action.
Slide 6: AWK Spoken Tutorials	Now, we will briefly go through some of the individual AWK tutorials in this series.
Tutorial: Basics of awk	Basics of awk This tutorial explains some basic operations in AWK like How to print the processed output and Using regular expressions
