How to Install Perl on Linux?

Prerequisite: Introduction to Perl Before, we start with the process of Installing Perl on our System. We must have first-hand knowledge of What the Perl Language is and what it actually does?. Perl is a general-purpose, high level interpreted and dynamic programming language. Perl was originally developed for text processing like extracting the required information from a specified text file and for converting the text file into a different form. Perl supports both procedural and Object-Oriented programming. Perl is a lot similar to C syntactically and is easy for the users who have knowledge of C, C++. Perl programs can be written on any plain text editor like gedit, notepad++, or anything of that sort. One can also use an online IDE for writing Perl codes or can even install one on their system to make it more feasible to write these codes. Using an IDE makes it easier to write Perl codes because IDEs provides a lot of features like intuitive code editor, debugger, compiler, etc. To begin with, writing Perl Codes and performing various intriguing and useful operations, one must have Perl installed on their System. This can be done by following the step by step instructions provided below:

Checking for a preinstalled Perl version:

Before we begin with the installation of Perl, it is good to check if it might be already installed on your system, because many software applications nowadays require Perl to perform their operations, hence a version of Perl might be included in the software's installation package and hence there is no need to redownload and install the Perl when it already exists. Many Linux systems have Perl preinstalled in their package. To check if your device is preinstalled with Perl or not, open the terminal using Ctrl+Alt+T. Now run the following command:

perl -v

If Perl is already installed, it will generate a message with all the details of the Perl's version available, otherwise if Perl is not installed then an error will arise stating Bad command or file name
