+
+ <refsect1><title>Description</title>
+ <para><command>apt</command> provides a high-level commandline interface for
+ the package management system. It is intended as an end user interface and
+ enables some options better suited for interactive usage by default
+ compared to more specialized APT tools like &apt-get; and &apt-cache;.
+ </para><para>
+ Much like <command>apt</command> itself, its manpage is intended as an end
+ user interface and as such only mentions the most used commands and options
+ partly to not duplicate information in multiple places and partly to avoid
+ overwhelming readers with a cornucopia of options and details.
+ </para>
+
+ <variablelist>
+ <varlistentry><term><option>update</option> (&apt-get;)</term>
+ <listitem><para><option>update</option> is used to download package
+ information from all configured sources. Other commands operate on
+ this data to e.g. perform package upgrades or search in and display
+ details about all packages available for installation.
+ </para></listitem>
+ </varlistentry>
+
+ <varlistentry><term><option>upgrade</option> (&apt-get;)</term>
+ <listitem><para><option>upgrade</option> is used to install available
+ upgrades of all packages currently installed on the system from the
+ sources configured via &sources-list;. New packages will be
+ installed if required to satisfy dependencies, but existing
+ packages will never be removed. If an upgrade for a package requires
+ the removal of an installed package the upgrade for this package
+ isn't performed.
+ </para></listitem>
+ </varlistentry>
+
+ <varlistentry><term><option>full-upgrade</option> (&apt-get;)</term>
+ <listitem><para><literal>full-upgrade</literal> performs the function of
+ upgrade but will remove currently installed packages if this is
+ needed to upgrade the system as a whole.
+ </para></listitem>
+ </varlistentry>
+
+ <varlistentry><term><option>install</option>, <option>reinstall</option>, <option>remove</option>, <option>purge</option> (&apt-get;)</term>
+ <listitem><para>Performs the requested action on one or more packages
+ specified via &regex;, &glob; or exact match. The requested action
+ can be overridden for specific packages by appending a plus (+) to the
+ package name to install this package or a minus (-) to remove it.
+ </para><para>
+ 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. Alternatively the version from a specific release can be
+ selected by following the package name with a forward slash (/) and
+ codename (&debian-stable-codename;, &debian-testing-codename;, sid …) or suite name (stable,
+ testing, unstable). This will also select versions from this release
+ for dependencies of this package if needed to satisfy the request.
+ </para><para>
+ Removing a package removes all packaged data, but leaves usually
+ small (modified) user configuration files behind, in case the
+ remove was an accident. Just issuing an installation request for the
+ accidentally removed package will restore its function as before in
+ that case. On the other hand you can get rid of these leftovers
+ by calling <command>purge</command> even on already removed
+ packages. Note that this does not affect any data or configuration
+ stored in your home directory.
+ </para></listitem>
+ </varlistentry>
+
+ <varlistentry><term><option>autoremove</option> (&apt-get;)</term>
+ <listitem><para>
+ <literal>autoremove</literal> is used to remove packages that were
+ automatically installed to satisfy dependencies for other packages
+ and are now no longer needed as dependencies changed or the package(s)
+ needing them were removed in the meantime.
+ </para><para>
+ You should check that the list does not include applications you have
+ grown to like even though they were once installed just as a
+ dependency of another package. You can mark such a package as manually
+ installed by using &apt-mark;. Packages which you have installed explicitly
+ via <command>install</command> are also never proposed for automatic removal.
+ </para></listitem>
+ </varlistentry>
+
+ <varlistentry><term><option>satisfy</option> (&apt-get;)</term>
+ <listitem><para><option>satisfy</option> satisfies dependency strings, as

+ </para></listitem>
+ </varlistentry>
+
+
+ <varlistentry><term><option>search</option> (&apt-cache;)</term>
+ <listitem><para><option>search</option> can be used to search for the given
+ &regex; term(s) in the list of available packages and display
+ matches. This can e.g. be useful if you are looking for packages
+ having a specific feature. If you are looking for a package
+ including a specific file try &apt-file;.

+ <varlistentry><term><option>show</option> (&apt-cache;)</term>
+ <listitem><para>Show information about the given package(s) including

+ <varlistentry><term><option>list</option></term>
+ <listitem><para><option>list</option> is somewhat similar to <command>dpkg-query --list</command>

+ <refsect1><title>Script Usage and Differences from Other APT Tools</title>
+ <para>
+ The &apt; commandline is designed as an end-user tool and it may
+ change behavior between versions. While it tries not to break
+ backward compatibility this is not guaranteed either if a change
+ seems beneficial for interactive use.
+ </para><para>
+ All features of &apt; are available in dedicated APT tools like &apt-get;
+ and &apt-cache; as well. &apt; just changes the default value of some
+ options (see &apt-conf; and specifically the Binary scope). So you should
+ prefer using these commands (potentially with some additional options
+ enabled) in your scripts as they keep backward compatibility as much as possible.
