Perl online training from india

Perl meant the Practical Extraction Report Language. However, programmers also refer to is as the Pathologically Eclectic Rubbish Lister. Or even, Practically Everything Really Likable. Perl is a programming language which can be used for a large variety of tasks. A typical simple use of Perl would be for extracting information from a text file and printing out a report or for converting a text file into another form. But Perl provides a large number of tools for quite complicated problems, including systems programming. Programs written in Perl are called Perl scripts, whereas the term the perl program refers to the system program named perl for executing Perl scripts.

Basic Perl concepts

Hi,

Greetings of the day

Here is today’s article for u

This article assumes that you already know how to program  know the C programming language, this will be especially easy for you. Perl is easy to use once you know the basics. In this article, we're going to start at the beginning and show you how to do the most common programming tasks using Perl. By the end of this article, you will be able to write your own Perl scripts with relative ease, and read cryptic scripts written by others with somewhat less ease, but this will be a good starting point.

         To start with Perl you need the Perl interpreter which already present in UNIX machine, where as in windows we have to download i.e. latest versions

PERL is a open source, DOCS directory that comes with Perl where u can find User manual

Once you have Perl loaded, make sure you have your path properly set to include the Perl executable. Then, open a text editor and create a text file. In the file, place the following line:

print "21cssindiacom\n";

Name the file "test1.pl". At the command prompt, type:

perl test1.pl

Perl will run and execute the code in the text file. You should see the words "21cssindia.com" printed to stdout (standard out). As you can see, it is extremely easy to create and run programs in Perl. (If you are using UNIX, you can place a comment like #! /usr/bin/perl on the first line, and then you will not have to type the word "perl" at the command line.)
The print command prints things to stdout. The \n notation is a line feed. That would be more clear if you modified the test program to look like this (# denotes a comment):

# Print on two lines

   print "21css \n indiacom\n";

Note that the print command understood that it should interpret the "\n" as a line feed and not as the literal characters. The interpretation occurred not because of the print command, but because of the use of double quotes (a practice called quoting in Perl). If you were to use single quotes instead, as in:

print '21css\nindiacom\n';

The \n character would not be interpreted but instead would be used literally.
There is also the backquote character: `. A pair of these implies that what is inside the quotes should be interpreted as an operating system command, and that command should be executed with the output of the command being printed. If you were to place inside the backquotes a command-line operation from the operating system, it would execute. For example, on Windows NT you can say:

print `cmd /c dir`;

to run the DIR command and see a list of files from the current directory.
You will also see the / character used for quoting regular expressions.
The print command understands commas as separators. For example:

print '21css', "\n", 'indiacom';

However, you will also see a period:

print '21cssindia'. "\n". 'com';

The period is actually a string concatenation operator.
There is also a printf operator for C folks.
PERL Note
In Windows NT, you cannot say:

print `dir`;

Because dir is not a separate executable -- it's part of the command interpreter cmd. Type cmd /? at a DOS prompt for details

Features of PERL

 PERL and its futures                                                                 For enquiry

        Perl is a programming language designed for processing text.             

It stands for Practical Extraction and Report Language.

If you have basic knowledge of C or UNIX Shell then PERL is very easy to learn! 

PERL Features

• Perl takes the best features from other languages, such as C, awk, sed, sh, and BASIC, among others.
• Perl database integration interface supports third-party databases including Oracle, Sybase, MySql and others.
• Perl works with HTML, XML, and other mark-up languages.
• Perl supports Unicode.
• Perl is Y2K compliant.
• Perl supports both procedural and object-oriented programming.
• Perl interfaces with external C/C++ libraries through XS or SWING
• Perl is extensible. There are over 500 third party modules available from the Comprehensive Perl Archive Network
• The Perl interpreter can be embedded into other systems.

PERL AND WEB

•          Perl is the most popular web programming language due to its text manipulation capabilities and     rapid development cycle.
•         Perl can handle encrypted Web data, including e-commerce transactions.
•         Perl can be embedded into web servers to speed up processing by as much as 2000%.

Execution process of perl

               Traditional compilers convert programs into machine language. When you run a Perl program, it's first compiled into a byte code, which is then converted ( as the program runs) into machine instructions. So it is not quite the same as shells, or Tcl, which are "strictly" interpreted without an intermediate representation. Nor it is like most versions of C or C++, which are compiled directly into a machine dependent format. It is somewhere in between, along with Python and awk and Emacs .elc files.

Prerequisites to be installed before installing Perl software in windows environment

Installing Prerequisites

• Install Perl on Microsoft Windows
• Download Active Perl
• Install Active Perl
• Verify Active Perl installation
• Download Apache HTTP server
• Install Apache HTTP server

Care to be taken before installing Apache server

                        Before installing Apache web server under Microsoft Windows, it is necessary to (ast least temporarily) shut down any other services listening on port number 80, such as the Microsoft Internet Information Server (IIS). To determine whether or not the IIS is already running, point your web browser to http://localhost/. If any web page is in fact served, shut down the IIS from within the Windows control panel.

• Start - Settings - Control Panel
• Administrative Tools - Services
• IIS Admin Service

Perl basic tutorial by 21cssindia

Perl basics

About PERL

          Perl is the Swiss Army chainsaw of scripting languages: powerful and adaptable. It was first developed by Larry Wall, a linguist working as a systems administrator for NASA in the late 1980s, as a way to make report processing easier. Since then, it has moved into a large number of roles: automating system administration, acting as glue between different computer systems; and, of course, being one of the most popular languages for CGI programming on the Web.

Why did Perl become so popular when the Web came along?

Two reasons:

          First, most of what is being done on the Web happens with text, and is best done with a language that's designed for text processing. More importantly, Perl was appreciably better than the alternatives at the time when people needed something to use. C is complex and can produce security problems (especially with untrusted data), Tcl can be awkward and Python didn't really have a foothold.

         It also didn't hurt that Perl is a friendly language. It plays well with your personal programming style. The Perl slogan is ``There's more than one way to do it,'' and that lends itself well to large and small problems alike.

      In this first part of our series, you'll learn a few basics about Perl and see a small sample program.

A Word about Operating Systems

               use a UNIX system preferably ,your Perl interpreter is located at/usr/local/bin/perl. fine when running Windows; most Perl code is platform-independent.

Your First Perl Program

Take the following text and put it into a file called first.pl:

     #!/usr/local/bin/perl

     print "Hi there!\n";

(Traditionally, first programs are supposed to say Hello world!, but I'm an iconoclast.)

Now, run it with your Perl interpreter. From a command line, go to the directory with this file and type perl first.pl. You should see:

     
Hi there!

      
       The \n indicates the ``newline'' character; without it, Perl doesn't skip to a new line of text on its own.
