apt (Advanced Packaging Tool) is a Shell front-end package manager for Debian and Ubuntu. The apt command provides commands to find, install, upgrade, and delete a single package, a group of packages, or even all packages. The commands are concise and easy to remember. The apt command requires super administrator privileges (root) to execute. ### apt Syntax apt [package ...] * **options:** Optional, options include -h (help), -y (answer "yes" to all prompts during installation), -q (do not show installation progress), etc. * **command:** The operation to perform. * **package**: The package name to install. * * * ## apt Common Commands * List all updatable packages command: sudo apt update * Upgrade software packages: sudo apt upgrade List updatable packages and version information: apt list --upgradable Upgrade software packages, remove packages that need to be updated first: sudo apt full-upgrade * Install specified package command: sudo apt install Install multiple packages: sudo apt install * Update specified package command: sudo apt update * Show detailed package information, such as: version number, installation size, dependencies, etc.: sudo apt show * Remove package command: sudo apt remove * Clean up unused dependencies and library files: sudo apt autoremove * Remove packages and configuration files: sudo apt purge * Find package command: sudo apt search * List all installed packages: apt list --installed * List version information for all installed packages: apt list --all-versions ### Examples View some updatable packages: sudo apt update !(#) Upgrade packages: sudo apt upgrade !(#) In the above interactive input, enter **Y** to start the upgrade. You can combine the following two commands for one-click upgrade: sudo apt install mplayer !(#) If you don't remember the full package name, you can enter only the first part of the package name and press Tab key to list related package names: !(#) In the above example, we entered **reds** and pressed Tab key, which output four related packages. If we want to install a package, but if the package already exists, do not upgrade it, we can use the --no-upgrade option: sudo apt install --no-upgrade Install mplayer, do not upgrade if it exists: sudo apt install mplayer --no-upgrade !(#) If you only want to upgrade, not install, you can use the --only-upgrade parameter: sudo apt install --only-upgrade Only upgrade mplayer, do not install if it doesn't exist: sudo apt install mplayer --only-upgrade !(#) If you need to set a specific version, the syntax is as follows: sudo apt install = **package_name** is the package name, **version_number** is the version number. To remove a package, you can use the remove command: sudo apt remove mplayer !(#) Find packages related to libimobile: apt search libimobile !(#) View information about the pinta package: apt show pinta !(#) List updatable packages: apt list --upgradeable !(#) Clean up unused dependencies and library files: sudo apt autoremove !(#) In the above interactive input, enter **Y** to start the cleanup.
