Perl, a high-level programming language developed by Larry Wall in 1987, is revered for its versatility in web development, system administration, network programming, and data analysis. Its popularity arises from its flexibility and extensive libraries, making it invaluable for developers and system administrators.

Installing Perl on Ubuntu is essential for running Perl scripts, developing applications, or utilizing Perl-based tools. As a popular Linux distribution, Ubuntu provides a convenient method to install Perl. This guide will walk you through the process step-by-step.

Prerequisites to Install Perl on Ubuntu

• Ubuntu Version Compatibility: This guide applies to Ubuntu versions 20.04, 18.04, and newer releases.
• Permissions: Sudo (administrator) privileges are necessary to execute commands that modify system files.
• Internet Connection: An active connection is required to download Perl packages from the Ubuntu repository or PPAs.

Installing Perl using the Ubuntu Repository

This method employs the official Ubuntu repository to install Perl, offering a stable and well-maintained version.

Step 1: Update the Package Lists

Open a terminal and execute this command to update package lists, ensuring you have the latest information about available packages:

sudo apt update && sudo apt upgrade

Step 2: Installing Perl on Ubuntu

Install the Perl package with:

sudo apt install perl

You'll be prompted for confirmation. Type ‘Y’ and press Enter to proceed.

Step 3: Verify Installation

Verify that Perl is installed correctly by running:

perl -v

This command will display the installed Perl version, confirming a successful installation.

Installing Perl using a Source

Installing Perl from source code offers more control and allows for customization to meet specific needs. Here’s how:

Step 1: Download the Perl Source Code

Use the wget command to download the Perl source code from the official CPAN website:

wget https://www.cpan.org/src/5.0/perl-5.34.0.tar.gz

Check the CPAN website for the latest version and update the URL accordingly.

Step 2: Extract the Source Code Archive

After downloading, extract it using:

tar -xvf perl-5.34.0.tar.gz

This command creates a directory named perl-5.34.0 containing the source code.

Step 3: Change into the Source Code Directory

Navigate into the perl-5.34.0 directory with:

cd perl-5.34.0

Step 4: Installing make Package

Install the make package, which is essential for building and installing software from source:

sudo apt install make

Step 5: Installing build-essential Package

The build-essential package provides essential build tools, imperative for compiling software:

sudo apt install build-essential

Step 6: Configure the Build

Run the configuration script to prepare the build environment:

./Configure -des -Dprefix=/usr/local/perl-5.36.0

Step 7: Build Perl

Use the make command to build Perl from the source code:

make

This step may take some time depending on your system’s capabilities.

Step 8: Install Perl

Finally, install Perl with:

make install

After these steps, you should have a working Perl installation on Ubuntu. Verify with:

perl -v

Conclusion

This guide provided step-by-step instructions for installing Perl on Ubuntu using two methods: the Ubuntu repository and source code. With Perl installed, you can now leverage its capabilities for various scripting tasks within Ubuntu.
