Perl, a high-level, general-purpose, interpreted, dynamic programming language, has been a staple in the development world for many years.
While it offers a range of features and is widely used for various tasks, there might be instances where you need to uninstall it from your Ubuntu system. Perhaps you’re migrating to a different language, or you need to resolve version conflicts, or maybe you’re just freeing up some space.
Whatever the reason, this guide will walk you through the process of removing Perl from your Ubuntu machine.
Let’s get started.
Step 1: Check the Installed Perl Version
Before proceeding with the uninstallation, it’s essential to determine which version of Perl is installed on your system. This will help you ensure that you’re removing the correct version.
sudo perl -v
This command will display the version of Perl currently installed on your system.
Step 2: List All Perl Packages
To get a comprehensive list of all Perl-related packages installed on your system, use the following command:
dpkg -l | grep perl
This command will provide a list of all packages related to Perl, which can be useful to ensure that all associated files and dependencies are removed.
Step 3: Uninstall Perl
Now that you’ve identified the Perl packages on your system, you can proceed to uninstall Perl using the following command:
sudo apt-get purge --auto-remove perl
This command will not only uninstall Perl but also remove its associated packages and configurations.
Step 4: Verify Uninstallation
After uninstalling, it’s always a good practice to verify that the uninstallation process was successful. Run the following command:
perl -v
If Perl has been successfully uninstalled, the system will notify you that the ‘perl’ command is not found.

- dpkg -l | grep perl – Lists all Perl-related packages.
- sudo apt-get purge –auto-remove perl – Uninstalls Perl and its associated packages and configurations.
