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: 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: 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. |
