First thing first What is the Perl Lenguage? Perl is a programming language, but it is not a language as we know it, it is a scripting language.
Perl is a widely used programming language for building CGI applications for the web. Perl is an acronym for Practical Extracting and Reporting Language, which indicates that it is a very practical programming language for extracting information from text files and generating reports from the content of the files.
Perl Lenguage Features
The Perl Lenguage it is inspired by languages like C, sh, awk and sed, this one is focused to be more practical and easier than the latter. That is why a programmer who has worked with the C language and the others will have less trouble understanding and using it quickly.
This is a free language for use, that means it is free. Before it was closely associated with the Uníx platform, but today it is available in other operating systems such as Windows.
This programming language is interpreted like many other Internet languages such as Javascript or ASP. This means that the code of the Perl scripts is not compiled but that each time it is to be executed the code is read and it starts interpreting what is written. It is also extensible from other languages, since from Perl we can make calls to subprograms written in other languages. Also from other languages we can execute Perl code.
If we want to work with Perl, it will be necessary to have the language interpreter installed. From that moment on we can run CGIs on our web servers. The process to achieve this may vary from one server to another, but they are usually placed in a special directory of the server called cgi-bin where we have placed the corresponding CGI permissions and as we have said before, this has been free to use and can be quite easy to master it and understand.
