|-
| 00:01
| Welcome to the''' Spoken Tutorial''' on''' Downloading CPAN modules.'''

|-
| 00:06
| In this tutorial we will learn how to download required '''CPAN modules '''in

* '''Ubuntu Linux Operating System '''and
* '''Windows Operating System'''

|-
| 00:17
| To record this tutorial, I am using

* '''Ubuntu Linux 12.04''' operating system
* '''Windows 7'''
* '''Perl 5.14.2 and'''
* '''gedit''' Text Editor

|-
| 00:32
| You can use any text editor of your choice.

|-
| 00:36
| To follow this tutorial, you should have working knowledge of''' Perl''' programming.

|-
| 00:41
| If not, then go through the relevant''' Perl''' spoken tutorials on the''' spoken tutorial''' website.

|-
| 00:48
| First we will learn how to download '''CPAN modules''' in''' Ubuntu Linux OS'''.

|-
| 00:55
| Switch to the '''terminal'''.

|-
| 00:57
| Type '''sudo''' space''' cpan''' and press '''Enter.''' Enter the password if required.

|-
| 01:06
| If cpan is not installed in your system, it will prompt you for the installation process.

|-
| 01:13
| Please proceed with the steps. Your computer must be connected to the internet for the installation process.

|-
| 01:21
| We can see the prompt changes to''' cpan'''.

|-
| 01:26
| Say for example, I want to extract some data from a '''CSV file''' and use in my '''Perl''' program.

|-
| 01:35
| For this, we will use''' Text colon colon CSV '''module.

|-
| 01:40
| Before using, we have to install the''' Text colon colon CSV module'''

|-
| 01:46
| Switch to the terminal.

|-
| 01:48
| Type''' Install Text colon colon CSV''' and press '''Enter.'''

|-
| 01:55
| We can see the installation of corresponding packages of this '''module'''.

|-
| 02:00
| Installation will take sometime to complete depending upon your internet speed.

|-
| 02:06
| Now let us check whether the '''module''' is installed successfully or not.

|-
| 02:12
| Hit the 'q' key to exit cpan.

|-
| 02:16
| Type''' instmodsh''' and press '''Enter'''.

|-
| 02:23
| Type''' l''' to list all installed '''modules'''.

|-
| 02:28
| Here we can see''' Text colon colon CSV, '''which shows that the modules is installed in our system.

|-
| 02:38
| Type 'q' to exit.

|-
| 02:41
| Now I will open the '''candidates.csv ''' which i have already saved.

|-
| 02:47
| Type gedit '''candidates.csv '''and press''' Enter.'''

|-
| 02:53
| Here we can see name, age, gender and email details of the candidates with a comma separator.

|-
| 03:02
| Now I will open '''csvtest.pl''' file in which I have written a '''Perl''' program that uses this '''module'''.

|-
| 03:11
| This program will extract the name field values which are stored in the''' csv file.'''

|-
| 03:18
| '''use '''statement loads the '''Text colon colon CSV module.'''

|-
| 03:23
| I have declared the '''candidates.csv''' file to a '''local variable''' dollar '''file'''.

|-
| 03:29
| The next statement will open the file in '''READ''' mode'''.'''

|-
| 03:34
| '''Text colon colon CSV''' is the class and we can create an instance, by calling the constructor with '''new.'''

|-
| 03:42
| This line creates an object setting the separator character to be comma (,).

|-
| 03:48
| Here, '''while''' loop fetches the data line by line using the '''getline''' '''method'''.

|-
| 03:54
| '''getline''' '''method''' returns a '''reference''' to an array.

|-
| 03:58
| We need to '''dereference''' it, to fetch the value.

|-
| 04:02
| Index of zero represents the name field in the csv file.

|-
| 04:07
| '''Print''' statement prints the names from the csv file.

|-
| 04:11
| Now, press''' Ctrl+S''' to save the file.

|-
| 04:15
| Let us execute the program.

|-
| 04:18
| Switch back to the''' terminal''' and type '''perl csvtest.pl''' and press''' Enter'''.

|-
| 04:27
| Here we can see names field as output.

|-
| 04:32
| Next, let us see how to download required''' CPAN''' modules in''' Windows Operating System.'''

|-
| 04:39
| When '''Perl '''is installed, a utility called''' PPM ie. Perl Package Module''' get installed automatically.

|-
| 04:48
| To use '''PPM''', your computer must be connected to the internet.

|-
| 04:53
| This utility can be used to

* search module
* install
* remove and
* upgrade

required '''modules '''on '''Windows Operating System'''.

|-
| 05:04
| Now let us open the command window in '''Windows OS'''.

|-
| 05:09
| To open the '''command window''', click on '''Start '''and type '''cmd '''and press '''Enter.'''

|-
| 05:17
| Type '''perl hyphen v ''' to''' '''check whether '''Perl''' is installed on your '''Windows OS machine'''.

|-
| 05:25
| You will see the '''Perl '''version number that is installed on your machine.

|-
| 05:30
| If '''Perl''' is not installed, refer to the '''Perl '''installation tutorial on this website.

|-
| 05:36
| It will tell you how to install '''Perl '''on '''Windows OS'''.

|-
| 05:41
| At the''' “DOS” prompt,''' type '''ppm install Text colon colon CSV''' and press '''Enter.'''

|-
| 05:49
| Please note, '''module''' names are case sensitive.

|-
| 05:53
| We can see the installation process has begun. Wait until the installation gets completed.

|-
| 06:00
| I have copied the '''candidates.csv''' and '''csvtest.pl''' file to the present working directory.

|-
| 06:08
| Let us execute the '''Perl '''program now.

|-
| 06:11
| In the '''command window''' type '''perl csvtest.pl''' and press''' Enter'''.

|-
| 06:18
| Here is the output.

|-
| 06:21
| This brings us to the end of this tutorial. Let us summarise.

|-
| 06:26
| In this tutorial we learnt about how to download required CPAN modules in

* '''Linux''' and
* '''Windows'''

|-
| 06:34
| Here is an assignment for you.
