  92. <refsect1><title>Description</title>
  93. <para><command>apt-get</command> is the command-line tool for handling packages, and may be
  94. considered the user's "back-end" to other tools using the APT
  95. library. Several "front-end" interfaces exist, such as &dselect;,
  96. &aptitude;, &synaptic;, &gnome-apt; and &wajig;.</para>
  97. <para>Unless the <option>-h</option>, or <option>--help</option> option is given, one of the
  98. commands below must be present.</para>
  99. <variablelist>
  100. <varlistentry><term>update</term>
  101. <listitem><para><literal>update</literal> is used to resynchronize the package index files from
  102. their sources. The indexes of available packages are fetched from the
  103. location(s) specified in <filename>/etc/apt/sources.list</filename>.
  104. For example, when using a Debian archive, this command retrieves and
  105. scans the <filename>Packages.gz</filename> files, so that information about new
  106. and updated packages is available. An <literal>update</literal> should always be
  107. performed before an <literal>upgrade</literal> or <literal>dist-upgrade</literal>. Please
  108. be aware that the overall progress meter will be incorrect as the size
  109. of the package files cannot be known in advance.</para></listitem>
  110. </varlistentry>
  111. <varlistentry><term>upgrade</term>
  112. <listitem><para><literal>upgrade</literal> is used to install the newest versions of all packages
  113. currently installed on the system from the sources enumerated in
  114. <filename>/etc/apt/sources.list</filename>. Packages currently installed with
  115. new versions available are retrieved and upgraded; under no circumstances
  116. are currently installed packages removed, or packages not already installed
  117. retrieved and installed. New versions of currently installed packages that
  118. cannot be upgraded without changing the install status of another package
  119. will be left at their current version. An <literal>update</literal> must be
  120. performed first so that <command>apt-get</command> knows that new versions of packages are
  121. available.</para></listitem>
  122. </varlistentry>
  123. <varlistentry><term>dselect-upgrade</term>
  124. <listitem><para><literal>dselect-upgrade</literal>
  125. is used in conjunction with the traditional Debian packaging
  126. front-end, &dselect;. <literal>dselect-upgrade</literal>
  127. follows the changes made by &dselect; to the <literal>Status</literal>
  128. field of available packages, and performs the actions necessary to realize
  129. that state (for instance, the removal of old and the installation of new
  130. packages).</para></listitem>
  131. </varlistentry>
  132. <varlistentry><term>dist-upgrade</term>
  133. <listitem><para><literal>dist-upgrade</literal> in addition to performing the function of
  134. <literal>upgrade</literal>, also intelligently handles changing dependencies
  135. with new versions of packages; <command>apt-get</command> has a "smart" conflict
  136. resolution system, and it will attempt to upgrade the most important
  137. packages at the expense of less important ones if necessary.
  138. The <filename>/etc/apt/sources.list</filename> file contains a list of locations
  139. from which to retrieve desired package files.
  140. See also &apt-preferences; for a mechanism for
  141. overriding the general settings for individual packages.</para></listitem>
  142. </varlistentry>
  143. <varlistentry><term>install</term>
  144. <listitem>
  145. <para>
  146. <literal>install</literal> is followed by one or more
  147. packages desired for installation or upgrading.
  148. Each package is a package name, not a fully qualified
  149. filename (for instance, in a Debian GNU/Linux system,
  150. libc6 would be the argument provided, not
  151. <literal>libc6_1.9.6-2.deb</literal>). All packages required
  152. by the package(s) specified for installation will also
  153. be retrieved and installed.
  154. The <filename>/etc/apt/sources.list</filename> file is
  155. used to locate the desired packages. If a hyphen is
  156. appended to the package name (with no intervening space),
  157. the identified package will be removed if it is installed.
  158. Similarly a plus sign can be used to designate a
  159. package to install. These latter features may be used
  160. to override decisions made by apt-get's conflict
  161. resolution system.
  162. </para>
  163. <para>A specific version of a package can be selected for installation by
  164. following the package name with an equals and the version of the package
  165. to select. This will cause that version to be located and selected for
  166. install. Alternatively a specific distribution can be selected by
  167. following the package name with a slash and the version of the
  168. distribution or the Archive name (stable, testing, unstable).</para>
  169. <para>Both of the version selection mechanisms can downgrade packages and must
  170. be used with care.</para>
  171. <para>This is also the target to use if you want to upgrade one or
  172. more already-installed packages without upgrading every package
  173. you have on your system. Unlike the "upgrade" target, which
  174. installs the newest version of all currently installed packages,
  175. "install" will install the newest version of only the package(s)
  176. specified. Simply provide the name of the package(s) you wish
  177. to upgrade, and if a newer version is available, it (and its
  178. dependencies, as described above) will be downloaded and
  179. installed.
  180. </para>
  181. <para>Finally, the &apt-preferences; mechanism allows you to
  182. create an alternative installation policy for
  183. individual packages.</para>
  184. <para>If no package matches the given expression and the expression contains one
  185. of '.', '?' or '*' then it is assumed to be a POSIX regular expression,
  186. and it is applied
  187. to all package names in the database. Any matches are then installed (or
  188. removed). Note that matching is done by substring so 'lo.*' matches 'how-lo'
  189. and 'lowest'. If this is undesired, anchor the regular expression
  190. with a '^' or '$' character, or create a more specific regular expression.</para></listitem>
  191. </varlistentry>
  192. <varlistentry><term>remove</term>
  193. <listitem><para><literal>remove</literal> is identical to <literal>install</literal> except that packages are
  194. removed instead of installed. If a plus sign is appended to the package
  195. name (with no intervening space), the identified package will be
  196. installed instead of removed.</para></listitem>
  197. </varlistentry>
  198. <varlistentry><term>purge</term>
  199. <listitem><para><literal>purge</literal> is identical to <literal>remove</literal> except that packages are
  200. removed and purged.</para></listitem>
  201. </varlistentry>
  202. <varlistentry><term>source</term>
  203. <listitem><para><literal>source</literal> causes <command>apt-get</command> to fetch source packages. APT
  204. will examine the available packages to decide which source package to
  205. fetch. It will then find and download into the current directory the
  206. newest available version of that source package. Source packages are
  207. tracked separately from binary packages via <literal>deb-src</literal> type lines
  208. in the &sources-list; file. This probably will mean that you will not
  209. get the same source as the package you have installed or as you could
  210. install. If the --compile options is specified then the package will be
  211. compiled to a binary .deb using dpkg-buildpackage, if --download-only is
  212. specified then the source package will not be unpacked.</para>
  213. <para>A specific source version can be retrieved by postfixing the source name
  214. with an equals and then the version to fetch, similar to the mechanism
  215. used for the package files. This enables exact matching of the source
  216. package name and version, implicitly enabling the
  217. <literal>APT::Get::Only-Source</literal> option.</para>
  218. <para>Note that source packages are not tracked like binary packages, they
  219. exist only in the current directory and are similar to downloading source
  220. tar balls.</para></listitem>

  230. <varlistentry><term>clean</term>
  231. <listitem><para><literal>clean</literal> clears out the local repository of retrieved package
  232. files. It removes everything but the lock file from
  233. <filename>&cachedir;/archives/</filename> and
  234. <filename>&cachedir;/archives/partial/</filename>. When APT is used as a
  235. &dselect; method, <literal>clean</literal> is run automatically.
  236. Those who do not use dselect will likely want to run <literal>apt-get clean</literal>
  237. from time to time to free up disk space.</para></listitem>
  238. </varlistentry>
  239. <varlistentry><term>autoclean</term>
  240. <listitem><para>Like <literal>clean</literal>, <literal>autoclean</literal> clears out the local
  241. repository of retrieved package files. The difference is that it only
  242. removes package files that can no longer be downloaded, and are largely
  243. useless. This allows a cache to be maintained over a long period without
  244. it growing out of control. The configuration option
  245. <literal>APT::Clean-Installed</literal> will prevent installed packages from being
  246. erased if it is set to off.</para></listitem>
  247. </varlistentry>
  248. <varlistentry><term>autoremove</term>
