| 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 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 (Basic of AWK from 04:09 to 04:15)--------------- | |
| 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 (Variables and Operators - 03:50 to 03:59 )------------- | |
| 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 | This tutorial also teaches how to write an AWK script. |
| 02:39 | Here is a glimpse of this tutorial. |
| ---------------Add the audio (Built-In variables -11:49 to 11:59 )------------ | |
| 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 (Conditional statements -02:50 to 03:02 )------------ | |
| 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 (Loops in awk -04:06 to 04:14 )------------ | |
| 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 (Basics of Single Dimensional Array - 03:10 to 03:22 )------------ | |
| 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 (More on Single Dimensional Array in awk from 04:59 to 05:09)------------ | |
| 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 (multidimensional array - 06:24 to 06:33 ) ------------ | |
| 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 (Built-in Functions - from 10:01 to 10:14)------------ | |
| 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 (User defined functions -03:28 to 03:41 )------------ | |
| 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. |
