How to use force uninstall technique to uninstall software in Linux?

Linux is a very stable and secure operating system because the software is designed to only access the resources it has been granted. This means that if you use Linux's default package manager to install software, it is also extremely easy to uninstall it. Moreover, sometimes you may encounter some software that is difficult to uninstall using the package manager. In this case, you need to use the forced uninstall method.

In this article, we will explain how to use the forced uninstall method to uninstall software in Linux. We'll cover three basic methods: using the command line, using uninstall tools, and automatically deleting files. Understanding this approach will help you better manage your Linux system.

Use the command line to force uninstall the software

The most common form of forcefully uninstalling software in Linux is to use the command line. Below are some commonly used commands:

1.Use dpkg command

dpkg is the core command of the Debian package manager. You can use it to manage deb packages (the format of Debian installation packages). If you want to uninstall a deb package, you can use the following command:

sudodpkg–remove–force-allpackage_name.deb

–dpkg: command name

––remove: Specify to delete the deb package

––force-all: Delete all files including uninstalled or damaged files

2.Use rpm command

rpm is the core command of the RedHat package manager. You can use it to manage rpm packages (the format of RedHat installation packages). If you want to uninstall an rpm package, you can use the following command:

sudorpm-e–forcepackage_name.rpm

–rpm: command name

–-e: Specify to uninstall the rpm package

––force: force uninstallation of packages, including damaged files

3. Use apt-get command

apt-get is the core command of Debian and Ubuntu package managers. You can use it to uninstall software installed on your Linux system. If you want to uninstall a software package, you can use the following command:

sudoapt-getremovepackage_name

–apt-get: command name

–remove: Specify to delete the software package

4.Use yum command

yum is the core command of CentOS and Fedora package managers. You can use it to uninstall installed software. If you want to uninstall a software package, you can use the following command:

sudoyumremovepackage_name

–yum: command name

–remove: Specify to delete the software package

Use the uninstall tool

Another way is to use an uninstall tool. Uninstall tools are generally easy to use and allow you to manually find residual files and delete them. Below are some commonly used uninstall tools:

1. Software Center Uninstall Tool

Most Linux distributions have an external software center from which you can install and uninstall software. The uninstall function in the Software Center will help you find and delete all software-related files and configurations. Using the Software Center uninstall tool can reduce the time required to uninstall software using the command line.

2.SynapticPackageManager

Synaptic Package Manager is a visual package manager that allows you to easily search and install packages and resolve dependency issues. It also has an available uninstall feature that allows you to find and remove all unnecessary packages.

Automatically delete files

Automatically deleting files is a relatively simple method, but these methods are risky because you may inadvertently delete a key file in the system. If you want to use these methods, be sure to back up your system in case something unexpected happens.

The following introduces how to automatically delete files:

1. Find the package name

Before you automatically uninstall the software, you need to know the package name of the software so that you know what files to delete. You can use the following command to find the name of a package:

sudoapt-cachesearchsoftware_name

2. Automatically delete files

After finding the software package name, use the following command to delete all files related to the software:

sudorm-rf/usr/share/software_name

–rm: command name

–-rf: Forcefully delete all files and directories (including subdirectories)

–/usr/share/software_name: the installation directory of the software package

In Linux, if you want to uninstall software, it is better to use the package manager. If you have difficulty uninstalling software using a package manager, you can use the command line, an uninstall tool, or automatically delete files. Remember, before using this method, you must back up your system to prevent accidents.

I hope this article can help you master the method of forcefully uninstalling software, allowing you to better manage your Linux system. I wish you a happy use!
