How To Install Perl on Rocky Linux 9

In this tutorial, we will show you how to install Perl on Rocky Linux 9. For those of you who didn’t know, Perl is a powerful scripting language used for various purposes such as web development, system administration, network programming, and more. Perl can run on multiple operating systems, including Unix/Linux, Windows, macOS, and more.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Perl scripting language on Rocky Linux. 9.

Prerequisites

• A server running one of the following operating systems: Rocky Linux 9.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Perl.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Perl on Rocky Linux 9

Step 1. The first step is to update your system to the latest version of the package list. To do so, run the following commands:

sudo dnf check-update
sudo dnf update

Step 2. Installing Perl on Rocky Linux 9.

By default, Perl is available on the Rocky Linux 9 base repository. Now we install the latest version of Perl using dnf the command:

sudo dnf install perl

You can use dnf to install additional packages for Perl. To do this, open the terminal and enter the following command:

sudo dnf install perl-<package_name>

Run the following command to check the version of Perl:

perl -v

Step 3. Testing Perl.

Here is an example of a simple “Hello World” script using Perl:

#!/usr/bin/perl

print "Hello, World!\n";

This script uses the print function to output the message “Hello, World!” to the console. The \n character sequence is used to insert a new line after the message. The first line #!/usr/bin/perl is known as a shebang and specifies the path to the Perl interpreter.

Save the above code to a file with an .pl extension, for example, hello_world.pl. Make sure to give the file execute permissions by running the command chmod +x hello_world.pl.

To run the script, open a terminal and navigate to the directory where the script is saved. Then, simply type the name of the script, like this:

./hello_world.pl
