00:01	Welcome to the spoken tutorial on PERL Overview and Installation of Perl.
00:08	In this tutorial, I'll take you through
00:10	* PERL Overview along with Installation steps for PERL on Ubuntu-Linux and Windows operating system.
00:20	For this tutorial:
0:21	You must be connected to the Internet.
00:25	You must have Ubuntu Linux and Windows Operating System.
00:30	For demonstration purpose, I will be using Ubuntu Linux 12.04 and Windows 7 operating system.
00:39	For Ubuntu Linux installation, you must have Synaptic Package Manager installed on your system.
00:47	You must have administrative rights.
00:50	And you must also have knowledge of using Terminal and Synaptic Package Manager in Ubuntu.
00:57	If not, please see the Linux series available on the spoken tutorial website.
01:03	Let me give you an overview of PERL Language.
01:07	PERL is an acronym which stands for Practical Extraction and Reporting Language.
01:14	It is a general-purpose programming language.
01:18	It was originally developed for text manipulation.
01:23	Now, it is used for web development, network programming, GUI development etc.
01:31	It is simple and very easy to understand.
01:35	It does not have complex data structures like in C or JAVA.
01:41	It is well known for pattern matching.
01:45	And most importantly, PERL is an open source language.
01:49	PERL comes pre-loaded on Ubuntu Linux 12.04 OS.
01:56	There is no specific procedure to be followed for installation.
02:01	Let us check the installed version of PERL on Ubuntu 12.04.
02:07	Open the terminal by pressing Ctrl + Alt + t simultaneously on the keyboard.
02:15	Then, type perl hyphen v
02:18	and then press ENTER.
02:21	You will get an output as displayed here, on the terminal.
02:26	This output shows us the current installed version of PERL.
02:31	In my case it is PERL 5.14.2 .
02:36	Let us check the default PERL packages available on Ubuntu 12.04.
02:43	Let's go to the launcher bar and click on Dash Home.
02:48	In the search bar, type Synaptic.
02:51	Synaptic Package Manager icon will be visible.
02:55	Click on it.
02:57	You will be prompted for your admin password, for Authentication purpose.
03:03	Enter your admin password and click on Authenticate.
03:08	Immediately, Synaptic Package Manager will load the package list.
03:13	This may take some time depending on your internet and system speed.
03:18	Once loaded, type Perl in Quick Filter.
03:22	You will see a list of packages.
03:25	The green color solid-filled check-box before a PERL package indicates that it is already installed.
03:33	Whereas check-boxes with star marks indicate that you may need these packages as well.
03:41	These will help you to create a documentation or debug a PERL script.
03:47	Install any of the missing packages depending on your future use of PERL.
03:54	Let us now go through the steps to install PERL on Windows Operating System.
04:00	At the time of recording the Perl tutorials, version 5.14.2 was available in Windows.
04:08	Now, there is a new PERL version available.
04:12	I will be demonstrating the installation using the new PERL version 5.16.3 .
04:19	All the PERL commands shown in the tutorials will work perfectly on the new version as well.
04:26	Open the browser on Windows Operating System,
04:30	and in the address bar, type the URL as shown.
04:35	You will be directed to the download page of PERL.
04:39	Select the download version as per your system specifications.
04:44	In my case, It will be 32 bit version of PERL.
04:49	Save the Perl msi file on your computer, in a location of your choice.
04:56	I have already saved it on my machine.
05:00	Open the folder where you have downloaded PERL msi file and double-click on it.
05:07	Then click on Run in the pop-up window.
05:11	Click on Next in the Setup Wizard window.
05:15	Accept the License Agreement when prompted and then click on Next.
05:21	Now, Custom Setup window will appear.
05:25	This window lists all the PERL features that get installed.
05:31	These are:
05:32	* Perl
05:33	* PPM utility, used to download and install Perl Modules on Windows
05:39	* Documentation which provides the documentation for Perl Modules and
05:44	* Examples of Perl.
05:47	Keep all these default features and click on Next.
05:52	A popup window for setting environmental variable and file extension will appear.
05:59	Keep the check-box checked, as shown here.
06:03	Click on Next and then Install.
06:07	This will start the installation of PERL.
06:11	This may take some time depending on your internet speed.
06:16	Once done, uncheck the Display release note check-box and then click on Finish.
06:23	This completes the installation of PERL on Windows.
06:27	Now let us verify the installation.
06:32	Go to Start menu and type cmd to open the command prompt.
06:39	On the command prompt, type: perl space hyphen v
06:44	and press ENTER.
06:46	You will see the installed version of PERL.
06:50	If it doesn't show the version, repeat the above installation steps once again.
06:57	Now let us execute a simple Hello Perl program.
07:02	This file has been provided to you along with this tutorial, in the "Code Files" link, below the player.
07:11	Please download and use this file.
07:14	I had saved the file in users\Amol directory on my system.
07:21	So, let's go there.
07:23	Then type: perl sampleProgram.pl
07:28	and press Enter.
07:30	Hello Perl will get printed on the command prompt,as shown.
07:35	Let us summarize.
