Cara menghapus aplication di Ubuntu

Cara menghapus aplication di Ubuntu

If you have an idea of what you want to uninstall, but you don’t know the exact name, see our article about finding out exact package names in Linux. You can also use the “dpkg” command to see a list of all installed packages on your computer, press “Ctrl + Alt + T” to open a Terminal window. Type the following command at the prompt and press “Enter”.
dpkg --list
NOTE: There are two dashes before “list”.
01_dpkg_list_command
Scroll through the list of installed packages in the Terminal window to find the one you want to uninstall. Note the full name of the package.
02_gimp_in_list
To uninstall a program, use the “apt-get” command, which is the general command for installing programs and manipulating installed programs. For example, the following command uninstalls gimp and deletes all the configuration files, using the “--purge” (there are two dashes before “purge”) command.
sudo apt-get --purge remove gimp
Enter your password when prompted and press “Enter”.
NOTE: The password does not display as you type it. However, you can choose to display asterisks as you type the password.
03_uninstalling_gimp_with_purge
The uninstallation process begins and a summary of the actions to be taken displays. When asked if you want to continue, type a “y” and press “Enter”.
04_do_you_want_to_continue
The installation process continues. When it’s done, type “exit” at the prompt and press “Enter” to close the Terminal window, or click the “X” button in the upper-left corner of the window.
05_closing_terminal_window
If you don’t want to remove the configuration files, simply leave out the “--purge” command, as shown in the following command.
sudo apt-get remove gimp
06_uninstalling_gimp_without_purge
As discussed in this article, programs installed in Linux depend on other packages to function. When you uninstall a program, there may be packages that the uninstalled program depended upon that are no longer used. To remove any unused packages, use the “autoremove” command, as shown in the following command.
sudo apt-get autoremove
07_running_autoremove_command
You can combine the two commands for removing a program and removing dependencies that are no longer being used into one, as shown below (again, two dashes before “auto-remove”).
sudo apt-get purge --auto-remove gimp
08_using_one_command_to_autoremove
If you’re short on space, you can use the “clean” command to remove downloaded archive files, as shown below.
sudo apt-get clean
This command removes the aptitude cache in “/var/cache/apt/archives”. When you install a program, the package file is downloaded and stored in that directory. You don’t need to keep the files in that directory. However, the only drawback of deleting them, is that if you decide to install any of those programs again, the packages would have to be downloaded again.
09_cleaning_apt_cache
The “apt-get” is a handy tool that makes downloading, installing, and uninstalling programs quick and easy. For more information about using the “apt-get” command, type “apt-get” at the prompt and press “Enter”.
