DESCRIPTION

       apt (Advanced Package Tool) is the command-line tool for handling
       packages. It provides a commandline interface for the package
       management of the system. See also apt-get(8) and apt-cache(8) 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 packages will be installed, but existing
           packages will never be 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.

OPTIONS

       All command line options may be set using the configuration file, the
       descriptions indicate the configuration option to set. For boolean
       options you can override the config file by using something like
       -f-,--no-f, -f=no or several other variations.

       -h, --help
           Show a short usage summary.

       -v, --version
           Show the program version.

       -c, --config-file
           Configuration File; Specify a configuration file to use. The
           program will read the default configuration file and then this
           configuration file. If configuration settings need to be set before
           the default configuration files are parsed specify a file with the
           APT_CONFIG environment variable. See apt.conf(5) for syntax
           information.

       -o, --option
           Set a Configuration Option; This will set an arbitrary
           configuration option. The syntax is -o Foo::Bar=bar.  -o and
           --option can be used multiple times to set different options.

SCRIPT USAGE

       The apt(8) 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(8) are available in apt-cache(8) and apt-get(8) via APT options.
       Please prefer using these commands in your scripts.

DIFFERENCES TO APT-GET(8)

       The apt command is meant to be pleasant for end users and does not need
       to be backward compatible like apt-get(8). 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.

DIAGNOSTICS

       apt returns zero on normal operation, decimal 100 on error.
