       apt - command-line interface

       apt [-h] [-o=config_string] [-c=config_file] [-t=target_release]
	   [-a=architecture] {list | search | show | update |
	   install pkg [{=pkg_version_number | /target_release}]...  |
	   remove pkg...  | upgrade | full-upgrade | edit-sources |
	   {-v | --version} | {-h | --help}}

       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 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 searches for the given term(s) and display matching

	   show shows the package information for the given package(s).

	   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,

	   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 lets you edit your sources.list file and provides
	   basic sanity checks.

	   update is used to resynchronize the package index files from their

	   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 performs the function of upgrade but may also remove
	   installed packages if that is required in order to resolve a
	   package conflict.

       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

       -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.

       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.

       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

       ·   The option DPkgPM::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 returns zero on normal operation, decimal 100 on error.
