To hire the top Perl companies, you should do a thorough research online. Based on the research, you need to shortlist a few. But it is difficult in case of an individual who has no knowledge in this field. We have listed here some of the top Perl companies that can provide you with better services.
Perl is a general-purpose programming language developed for text manipulation and used for web development, system administration, network programming, code generation and more. It supports both procedural and object-oriented programming. Perl has certain inbuilt functions that the programming language uses tools for sorting and making the operating system respond.
CGI, or Common Gateway Interface, is a standard of communication between a web server and a client, such as a user with a web browser Perl is a very common language for CGI programming as it is largely platform independent and the language’s features make it very easy to write powerful applications. Perl is a very common language for CGI programming as it is largely platform independent and the language’s features make it very easy to write powerful applications.
The subroutines and variables which are reusable in Perl are stored to form a collection. This collection is called a module. A package is a logical subdivision of compiled code In which variables and subroutines can reside. Subroutines in Perl is a code block which can be reused multiple times. They are defined by a keyword sub.
As Perl executes a script, it keeps run-time information in several stacks, the most important one being the "argument stack," or stack as it is simply known in the Perl source. Perl can conduct automatic data typing and management of the memory. Perl supports three main types of variables:
Perl includes a number of popular UNIX facilities such as sed, awk, and tr. It can be compiled just before execution into either C code or cross-platform bytecode. A plug-in can be installed for some servers, such as Apache, so that Perl is loaded permanently in memory, thus reducing compile time and resulting in faster execution of CGI Perl scripts.
Some of the features are given below:
1.Perl is a cross-platform language, it is very easy to write a Perl program on one platform and run it across different platforms with little or no modification.
2.The programmer can learn the language and adapt their own coding style. It is versatile in nature.
3.Perl has a very comprehensive library of modules which provides a very support for XML, Graphical user interfaces and embedded Perl scripting.
4.It supports multiple platforms such as Linux-Unix, Microsoft DOS and Windows and Apple Mac’s as well as some mobile platforms also.
5.It provides a regular expression engine which is capable of almost any type of textual transformation. This feature is the one reason for its popularity between programmer for both command line and programming.
