|-
|| 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

|-
|| Tutorial: Variables and Operators
|| '''Variables and Operators'''

Here we will learn how to use -

*'''User defined variables'''
*'''Variable''' initialisation
*'''Operators'''
*'''String Concatenation''' & matching '''operator'''
*'''BEGIN''' and '''END statement''' in '''AWK'''

|| Let’s have a look at this tutorial.
|-
|| Tutorial: Loops
|| '''Loops'''-

Here we will discuss about

*'''Conditional loops''' in '''AWK''' like '''for, while''' and '''do-while loop'''
*We also learn '''search pattern''' using '''AWK'''
*Process data from a single or multiple files

|-
|| Glimpse of tutorial
|| Let’s take a look at this tutorial.

|-
|| Tutorial: Basics of Single Dimensional Array
|| Basics of '''Single Dimensional Array''' tutorial explains

*Assigning '''array elements'''
*Refer the '''elements''' of an '''array'''
*Indexing '''AWK arrays '''
*Advantage of '''associative array'''
*Checking whether any '''element '''exists in an '''array '''at a certain index

|-
|| Glimpse of tutorial
|| Here is a glimpse of this tutorial.

|-
|| Tutorial: More on Single Dimensional Array
|| This advanced level tutorial on '''Single dimensional array''' explains

*Using '''AWK array '''with file
*Scan the '''elements '''of an '''array '''
*New variation of "'''for loop'''"
*Delete an '''array element'''
*Delete the whole '''array'''
*Values of '''ARGC '''and '''ARGV'''

|-
|| Glimpse of tutorial
|| Let’s have a look at this tutorial.

|-
|| Tutorial: Multi Dimensional Array
|| '''Multi Dimensional Array''' in '''AWK''' explains

*Identifying an '''element''' by a sequence of multiple indices
*Concatenated into a single '''string'''
*Create 2 by 2 '''multidimensional array''' in '''AWK'''
*Create the '''transpose''' of a 2 by 2 '''matrix'''
*Scan the '''multidimensional array '''
*Combine the '''for loop''' with the '''split function'''
