To completely remove Jenkins from a Linux system, you can follow these steps:

1. Stop the Jenkins service: Open a terminal. Run the command: sudo systemctl stop jenkins.
2. Uninstall Jenkins: Depending on your Linux distribution, there are different package managers you can use. Choose the appropriate one from below: If using Debian/Ubuntu-based systems (apt): Run the command: sudo apt-get remove jenkins. If using Red Hat-based systems (yum/dnf): Run the command: sudo yum remove jenkins or sudo dnf remove jenkins. If using openSUSE (zypper): Run the command: sudo zypper remove jenkins.
3. Remove Jenkins configuration and data files: Run the command: sudo rm -rf /var/lib/jenkins (This will remove all configuration and data of Jenkins). Run the command: sudo rm -rf /var/cache/jenkins (This will remove any cached files). Run the command: sudo rm -rf /var/log/jenkins (This will remove Jenkins logs). Run the command: sudo rm -rf /etc/default/jenkins (This will remove the Jenkins configuration file).
4. Confirm removal: Run the command: dpkg -l | grep jenkins (or the equivalent command for your package manager). Make sure that Jenkins is not listed as an installed package.

By following these steps, you will completely remove Jenkins and all its associated files and configurations from your Linux system.

It is also a good practice to take a backup of any important Jenkins data or configurations before proceeding with the uninstallation process to avoid permanent data loss.
