CentOS is a reliable and secure operating system based on the source code of Red Hat Enterprise Linux (RHEL). Like any other operating system, CentOS comes pre-installed with several packages that might not be necessary for your specific needs. In such cases, uninstalling these packages could help you free up valuable disk space and optimize your system’s performance. In this article, we will guide you through the process of uninstalling packages in CentOS using the yum package manager and the rpm command-line tool. So, let’s get started!
When it comes to uninstalling apps from your device, there are a few things to keep in mind. First and foremost, it’s important to understand that the process can vary depending on the platform you’re using. For example, uninstalling an app on an Android device may be slightly different than uninstalling an app on an iOS device.
Uninstalling Apps on Android Devices
If you’re using an Android device, there are a few different ways to uninstall an app. One way is to go to your device’s Settings menu and select “Apps.” From there, you can find the app you want to uninstall and tap on it. This should bring up a screen with information about the app, including an option to uninstall it. Simply tap on “Uninstall,” and the app will be removed from your device.
Another way to uninstall apps on an Android device is to simply long-press on the app icon on your home screen or app drawer. This should bring up a menu with options to uninstall or remove the app. Again, simply select “Uninstall,” and the app will be removed from your device.
Uninstalling Apps on iOS Devices
If you’re using an iOS device, the process for uninstalling apps is a bit different. To start, you’ll need to find the app you want to uninstall on your home screen. Once you’ve found it, simply press and hold on the app icon until it starts to jiggle. You should then see a small “x” appear in the corner of the app icon.
Click on the “x” and you’ll be prompted to confirm that you want to delete the app. Click “Delete” and the app will be removed from your device.
Uninstalling Apps on Other Platforms
If you’re using a platform other than Android or iOS, the process for uninstalling apps may vary. For example, Windows devices have a different process for uninstalling apps than Mac devices. It’s important to check with the manufacturer of your device to understand how to uninstall apps on your specific platform.
Removing Pre-Installed Apps
In some cases, you may not be able to uninstall certain apps from your device. This is often the case with pre-installed apps that come with your device. While you may not be able to fully uninstall these apps, you may be able to disable them so that they don’t take up as much space or use as much battery life.
To disable a pre-installed app on an Android device, go to your device’s Settings menu and select “Apps.” From there, find the app you want to disable and tap on it. You should see an option to “Disable” the app. Tap on this option, and the app will be disabled.
On an iOS device, you can’t fully disable pre-installed apps, but you can remove their icons from your home screen. To do this, simply press and hold on the app icon until it starts to jiggle, then click on the “x” to remove the icon from your home screen.
Conclusion
Uninstalling apps from your device is a simple process that can help you free up space, improve performance, and customize your device to better suit your needs. Whether you’re using an Android or iOS device, understanding how to uninstall apps can help you get the most out of your device.

Where package_name is the name of the package you want to uninstall.
If you want to remove a package and its dependencies, you can use the autoremove option:

How to uninstall a package in rpm CentOS?
To uninstall a package in rpm CentOS, you can use the rpm command with the -e option followed by the name of the package.
First, open a terminal and type the following command to list all installed packages:
“`
rpm -qa
“`
This will display a long list of all the packages installed on your system. Find the name of the package you want to uninstall from this list.
Next, use the rpm -e command followed by the name of the package to uninstall it. For example, if you want to uninstall the package named “example_package”, type the following command:

“`
This will remove the package from your system.
You can also use the –nodeps option with the rpm -e command to force the removal of the package even if other packages depend on it. However, this should be used with caution as it may cause issues with other packages.
That’s it! The package has been successfully uninstalled from your CentOS system using the rpm command.

1. Open the terminal and log in as root or use sudo to gain root privileges.

How to remove all packages from CentOS 8?
To remove all packages from CentOS 8, you can use the yum package manager. First, you need to install the yum-utils package by running the following command:

Once installed, use the package-cleanup command with the –all and –leaves options to remove all packages that are not dependencies of any other installed package:
