It provides a commandline interface for the package management of the system. See also &apt-get; and &apt-cache; for more low-level command options. list list is used to display a list of packages. It supports shell pattern for matching package names and the following options: --installed, --upgradable, --all-versions are supported. search search searches for the given term(s) and display matching packages. show show shows the package information for the given package(s). install install is followed by one or more package names desired for installation or upgrading. A specific version of a package can be selected for installation by following the package name with an equals and the version of the package to select. This will cause that version to be located and selected for install. Alternatively a specific distribution can be selected by following the package name with a slash and the version of the distribution or the Archive name (stable, testing, unstable). remove remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed. edit-sources edit-sources lets you edit your sources.list file and provides basic sanity checks. update update is used to resynchronize the package index files from their sources. upgrade upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. New package will be installed, but existing package will never removed. full-upgrade full-upgrade performs the function of upgrade but may also remove installed packages if that is required in order to resolve a package conflict. &apt-cmdblurb; &apt-commonoptions; The &apt; commandline is designed as a end-user tool and it may change the output between versions. While it tries to not break backward compatibility there is no guarantee for it either. All features of &apt; are available in &apt-cache; and &apt-get; via APT options. Please prefer using these commands in your scripts. The apt command is meant to be pleasant for end users and does not need to be backward compatible like &apt-get;. Therefore some options are different: The option DPkg::Progress-Fancy is enabled. The option APT::Color is enabled. A new list command is available similar to dpkg --list. The option upgrade has --with-new-pkgs enabled by default. &apt-get;, &apt-cache;, &sources-list;, &apt-conf;, &apt-config;, The APT User's guide in &guidesdir;, &apt-preferences;, the APT Howto. apt returns zero on normal operation, decimal 100 on error. &manbugs;
