A Summary Tutorial of Perl Basics Features
Perl Basics features - this tutorial is a great opportunity to master and improve your skill in using Perl language. Perl is an open-source server-side programming language and one of the most popular web programming language. It is also a cross platform programming language and supports vary operating systems such as Unix, Windows, Solaris, Macintosh. Before playing with Perl, you must check if you have Perl installed on your computer. Some operating systems such as Linux and Unix have already installed Perl, so all you have to do is to use it. If you need some more information about how to install Perl or see its version, please see one of the links at the bottom of the page.
A Perl program is called script and can be created with any text editor and saved in a file with the extension .pl. But if you want to see highlighting syntax or some other important editing features, we suggest you to use some dedicate editor - see also our link :
