How to Install Perl on Ubuntu

Perl, an acronym for Practical Extraction and Reporting Language, is a versatile and powerful programming language that has been a cornerstone in the web development and system administration world for decades. Its text processing capabilities, combined with its cross-platform compatibility, make it an essential tool for many webmasters and system administrators.

In this guide, we will walk you through the steps to install Perl on an Ubuntu system. By the end of this tutorial, you’ll have a functional Perl environment ready for development or administration tasks.

Let’s get started.

Step 1: Update Your System

Before installing any new software, it’s always a good practice to update your system’s package repository. This ensures that you’re getting the latest versions and patches.

sudo apt update && sudo apt upgrade -y

Step 2: Install Perl

Ubuntu usually comes with Perl pre-installed. However, to ensure you have it or to install the latest version, run:

sudo apt install perl

Step 3: Verify Perl Installation

After installation, you can verify the version of Perl installed:

perl -v

This command will display the version of Perl that’s been installed, along with some licensing information.
