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.
For example:
geeks@ubuntu:~# perl -v This is perl 5, version 26, subversion 1 (v5.26.1) built for x86_64-linux-gnu-thread-multi (with 79 registered patches, see perl -V for more detail) Copyright 1987-2017, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit. Complete documentation for Perl, including FAQ lists, should be found on this system using "man perl" or "perldoc perl". If you have access to the Internet, point your browser at http://www.perl.org/, the Perl Home Page.
Step 4: Install CPAN
CPAN, or the Comprehensive Perl Archive Network, is a repository of Perl modules. It’s a valuable resource for Perl developers. To install it:
sudo apt install cpanminus
Step 5: Using CPAN to Install Perl Modules
With CPAN installed, you can easily fetch and install Perl modules. For instance, to install the “Try::Tiny” module:
cpanm Try::Tiny
Commands Mentioned
- sudo apt update && sudo apt upgrade -y – Updates the system’s package repository.
- sudo apt install perl – Installs Perl.
- perl -v – Displays the installed Perl version.
- sudo apt install cpanminus – Installs CPAN.
- cpanm [ModuleName] – Installs a Perl module from CPAN.
