|-
| 00:01
| Welcome to the spoken tutorial on Variables in '''Perl'''.

|-
| 00:06
| In this tutorial, we will learn about Variables in '''Perl'''

|-
| 00:12
| I am using '''Ubuntu Linux12.04''' operating system and

|-
| 00:18
| '''Perl''' '''5.14.2 ''' that is, '''Perl''' revision 5 version 14 and subversion 2

|-
| 00:26
| I will also be using the '''gedit Text Editor'''.

|-
| 00:30
| You can use any text editor of your choice.

|-
| 00:34
| '''Variables''' in '''Perl''':

|-
| 00:37
| '''Variables''' are used for storing values, like text strings, numbers or arrays.

|-
| 00:44
| Once a '''variable''' is declared, it can be used over and over again in the script.

|-
| 00:50
| '''Scalar''' represents a single value and can store '''scalars''' only.

|-
| 00:56
| '''Scalar variables''' are declared using $ ('''dollar''') symbol.

|-
| 01:00
| Let us look at '''Variable Declaration''':

|-
| 01:03
| A '''variable''' can be declared as follows: '''dollar priority semicolon'''

|-
| 01:09
| '''Variable''' names in '''Perl''' can have several formats. '''Variables''' must begin with a letter or '''underscore'''

|-
| 01:18
| And may contains letters, digits, '''underscores''' or a combination of above 3.

|-
| 01:24
| '''Variables''' declared with CAPITAL letters have special meaning in '''Perl.'''

|-
| 01:30
| So avoid declaring '''variables''' using Capital letters.

|-
| 01:34
| Now open the '''Terminal''' and type '''gedit variables dot pl ampersand '''

|-
| 01:44
| The '''ampersand''' will unlock the command prompt on the '''terminal'''. Now press '''Enter'''.

|-
| 01:50
| This will open the '''variables.pl '''file in '''gedit''' text editor.

|-
| 01:56
| '''dot pl '''is the default extension of a '''Perl''' file.

|-
| 02:01
| Type the following in the file; '''dollar priority semicolon''' and press '''Enter'''.

|-
| 02:10
| So we have declared the '''variable priority'''.

|-
| 02:13
| You do not need to declare a '''variable''' before using it;

|-
| 02:18
| you can just use it into your code.

|-
| 02:21
| Now let us assign a numerical value to the '''variable priority'''.

|-
| 02:25
| For this type '''dollar priority space equal to space one semicolon'''

|-
| 02:32
| and press '''Enter'''.

|-
| 02:34
| Next, type

|-
| 02:36
| '''print space double quote Value of variable is: dollar priority slash n''' close double quote '''semicolon''' and press enter

|-
| 02:50
| '''slash n''' is the new line character.

|-
| 02:53
| Now save this file as '''variables.pl''' at any location.

|-
| 03:02
| In my case, it will get saved in '''home/amol '''directory. Now save this file

|-
| 03:10
| Now, let us change the permissions of '''variables.pl''' file, which we just now created.

|-
| 03:18
| To do so, on the '''Terminal''' type, '''chmod 755 variables dot pl'''

|-
| 03:27
| This will provide read, write & execute rights to the file.

|-
| 03:32
| To compile this '''Perl''' script, on the '''Terminal'''

|-
| 03:36
| type ;'''perl hyphen c variables dot pl'''

|-
| 03:42
| '''Hyphen c '''switch compiles the '''Perl''' script for any compilation/syntax error.

|-
| 03:49
| Now press '''Enter'''

|-
| 03:51
| This tells us that there is no syntax error in our script.

|-
| 03:56
| Now let's execute the '''Perl''' script by typing '''perl variables dot pl''' and press '''Enter'''.

|-
| 04:06
| The output displayed is as highlighted.

|-
| 04:10
| We can also assign a '''string''' value to the '''variable''' we declared.

|-
| 04:15
| Switch back to the Text editor window.

|-
| 04:18
| Instead of '''dollar priority equal to one;''' type

|-
| 04:22
| '''dollar priority equal to in single quote high '''

|-
| 04:28
| Please note that the assignments are evaluated from right to left.

|-
| 04:34
| A '''scalar''' can hold data of any type, be it a '''string''', a number

|-
| 04:38
| Save this file and compile the script once again by typing

|-
| 04:45
| '''perl hyphen c variables dot pl''' now press '''Enter'''.

|-
| 04:51
| This tells us that there is no syntax error.

|-
| 04:55
| Execute the script by typing '''perl variables dot pl''' and press '''Enter'''.

|-
| 05:03
| The output is as shown.

|-
| 05:07
| Now switch back to the Text Editor window.

|-
| 05:10
| You can also use '''scalars''' within a double-quoted '''strings''' as

|-
| 05:15
| '''dollar priority in double quote String'''

|-
| 05:19
| Save this file and close it.

|-
| 05:22
| let us learn how to declare multiple '''variables'''.

|-
| 05:27
| To do so open the new file in Text Editor.

|-
| 05:31
| on'''Terminal''' type - '''gedit multivar dot pl space ampersand''' and press '''Enter'''.

|-
| 05:42
| This will open '''multivar dot pl''' file in text editor

|-
| 05:48
| Now type -

|-
| 05:50
| '''dollar firstVar comma dollar secondVar semicolon''' and press '''Enter'''.

|-
| 06:00
| To copy the value of variable '''dollar firstVar''' to '''dollar secondVar''', type -

|-
| 06:07
| '''dollar firstVar space equal to space dollar secondVar semicolon''' and press '''Enter'''.

|-
| 06:19
| All mathematical operations like addition, subtraction, multiplication, division, can be done on these variables

|-
| 06:30
| Let us see how we can achieve this using '''Perl'''.

|-
| 06:34
| Switch to text editor.

|-
| 06:36
| And now let us assign the value '''10''' to both of these variables by typing,

|-
| 06:41
| '''dollar firstVar equal to dollar secondVar equal to ten semicolon''' And Press '''Enter'''.

|-
| 06:51
| Now to print these values, type

|-
| 06:55
| '''print double quote firstVar: dollar firstVar and secondVar: dollar secondVar slash n''' close double quote '''semicolon''' press '''Enter'''.

|-
| 07:17
| Now save this file.

|-
| 07:19
| Now let us add the values in the two variables.

|-
| 07:23
| For this type

|-
| 07:25
| '''dollar addition space equal to space dollar firstVar plus space dollar secondVar semicolon'''and Press '''Enter'''.

|-
| 07:43
| Notice, we haven't declared the variable '''addition'''.

|-
| 07:47
| Once again, to print the value of the variable '''addition''', type

|-
| 07:53
| '''print double quote Addition is dollar addition slash n''' close double quote '''semicolon'''

|-
| 08:05
| Save this file

|-
| 08:07
| To compile this file again on terminal type

|-
| 08:12
| '''perl hyphen c multivar dot pl'''

|-
| 08:18
| There is no syntax error so we can execute the script...

|-
| 08:24
| by typing '''perl multivar dot pl'''

|-
| 08:30
| This will produce an output as highlighted.

|-
| 08:34
| Similarly, try subtraction, multiplication and division.

|-
| 08:38
| I have written the code here.

|-
| 08:41
| Now let us save this file and close it.

|-
| 08:46
| Now compile the file by typing

|-
| 08:48
| '''perl hyphen c multivar dot pl'''

|-
| 08:54
| There is no syntax error.

|-
| 08:55
| So we can execute the script as '''perl multivar dot pl'''

|-
| 09:01
| On execution the output will look like this.

|-
| 09:06
| This brings us to the end of this tutorial.

|-
| 09:11
| In this tutorial we have learnt,

|-
| 09:14
| To Declare and Use '''scalar variables''' in '''Perl'''

|-
| 09:18
| '''Assignment'''

|-
| 09:20
| Declare a number '''variable'''.
|-
| 09:22
| Assign 10 to it.
|-
| 09:24
| Print the '''variable''' declared.
|-
| 09:26
| Declare 2 '''string variables'''.
|-
| 09:29
| Assign these values to them - “Namaste ” and “India”.
|-
| 09:34
| Print those '''2 variables''' one after the other.
