| 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 Linux12.04 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 | Therefore, 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 checkbox before a PERL package indicates that it is already installed. |
| 03:33 | Whereas checkboxes 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 Aggrement 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 utilty, used to download and install Perl Modules on Windows |
| 05:39 | Documentation which provides the documentation for Perl Modules |
| 05:44 | And 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 checkbox and then click on Finish. |
| 06:23 | This completes the installation of PERL on Windows. |
| 06:23 | 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 | Pls 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. |
