Perl is a programming language developed by Larry Wall, especially 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! 
You definitely will enjoy it! 

What is PERL?

  • Perl is a stable, cross platform programming language.
  • Perl stands for Practical Extraction and Report Language.
  • It is used for mission critical projects in the public and private sectors.
  • Perl is Open Source software, licensed under its Artistic License, or the GNU General Public License (GPL).
  • Perl was created by Larry Wall.
  • Perl 1.0 was released to usenet’s alt.comp.sources in 1987
  • PC Magazine named Perl a finalist for its 1998 Technical Excellence Award in the Development Tool category.
  • Perl is listed in the Oxford English Dictionary.

Supported Operating Systems

PERL Features

  • Perl takes the best features from other languages, such as C, awk, sed, sh, and BASIC, among others.
  • Perls database integration interface (DBI) supports third-party databases including Oracle, Sybase, PostgresMySQL 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 SWIG.
  • Perl is extensible. There are over 500 third party modules available
  • from the Comprehensive Perl Archive Network (CPAN).

  • The Perl interpreter can be embedded into other systems.

PERL and the Web

  • Perl is the most popular web programming language due to its text manipulation capabilities and rapid development cycle.
  • Perl is widely known as ” the duct-tape of the Internet“.
  • Perl’s CGI.pm module, part of Perl’s standard distribution, makes handling HTML forms simple.
  • 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%.
  • mod_perl allows the Apache web server to embed a Perl interpreter.
  • Perl’s DBI package makes web-database integration easy.

Is Perl Compiled or Interpreted

Good question. The sort answer is interpreted, which means that your code can be run as is, without a compilation stage that creates a non-portable executable program.

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 andawk and Emacs .elc files.
