Time	Narration
00:01	Hello and welcome to the spoken tutorial on Overview of Linux AWK commands.
00:08	In this tutorial we will learn about Linux AWK and The tutorials covered in the Linux AWK series
00:17	To record this tutorial, I am using Ubuntu Linux 16.04 Operating System
00:24	AWK is a used for searching and extracting data from a file.
00:30	We can also manipulate the data and generate reports using AWK.
00:36	Like any programming language, AWK also has Variables Operators
00:41	Conditional Statements Loops
00:45	Single and Multi Dimensional Arrays Built-in Functions and User Defined functions
00:52	During the search process- A file will be treated as a sequence of records.
00:58	Each line will be considered as a single record with multiple fields.
01:04	Then AWK searches for the given pattern. And performs the desired action.
01:11	Now, we will briefly go through some of the individual AWK tutorials in this series.
01:18	Basics of awk This tutorial explains some basic operations in AWK like
01:25	How to print the processed output and Using regular expressions
01:31	Let’s have a look at this tutorial.
	------------Add the audio---------------
01:43	Variables and Operators Here we will learn how to use - User defined variables
01:51	Variable initialisation Operators
01:55	String Concatenation & matching operator BEGIN and END statement in AWK
02:03	Let’s have a look at this tutorial.
	----------Add the audio-------------
02:16	Built-In variables
02:18	This tutorial explains about the following built-in variables in AWK like:
02:24	RS, FS ORS, OFS NR, NF ARGV, ARGC
02:34	The tutorial also teaches how to write an AWK script.
02:39	Here is a glimpse of this tutorial.
	---------------Add the audio------------
02:53	Conditional statements In this tutorial, we will learn how to use the conditional statements like: If, else , else if in awk
03:04	Let’s have a look at this tutorial.
	---------------Add the audio------------
03:21	Loops- Here we will discuss about Conditional loops in AWK like for, while and do-while loop
03:31	We will also learn search pattern using AWK
03:35	Process data from a single or multiple files
03:40	Let’s take a look at this tutorial.
	---------------Add the audio------------
03:53	Basics of Single Dimensional Array tutorial explains Assigning array elements
03:59	Refer the elements of an array Indexing AWK arrays
04:04	Advantage of associative array
04:07	Checking whether any element exists in an array at a certain index
04:14	Here is a glimpse of this tutorial.
	---------------Add the audio------------
04:30	This advanced level tutorial on Single dimensional array explains Using AWK array with file Scan the elements of an array
04:41	New variation of "for loop" Delete an array element
04:47	Delete the whole array
04:50	Values of ARGC and ARGV
04:54	Let’s have a look at this tutorial.
	---------------Add the audio------------
05:08	Multi Dimensional Array in AWK explains
05:12	Identifying an element by a sequence of multiple indices
05:17	Concatenated into a single string
05:20	Create 2 by 2 multidimensional array in AWK
05:24	Create the transpose of a 2 by 2 matrix
05:28	Scan the multidimensional array
05:31	Combine the for loop with the split function
05:35	Let’s take a look at this tutorial.
	---------------Add the audio------------
05:48	Built-in Functions. In this we will learn about AWK built-in functions like: Arithmetic functions
05:57	Random functions String functions
06:01	Input and Output functions and Timestamp functions
06:07	Here is a glimpse of this tutorial.
	---------------Add the audio------------
06:23	In User defined functions tutorial, we will learn How to create our own function
06:30	Function call Return statement and Reverse function
06:37	Here is a glimpse of this tutorial.
	---------------Add the audio------------
06:54	With this we come to the end of this tutorial. Let us summarise
07:00	In this tutorial, we learnt about AWK and went through the tutorials in this series.
