111 | <refsect1><title>Description</title> | |
112 | <para><command>apt-get</command> is the command-line tool for handling packages, and may be | |
113 | considered the user's "back-end" to other tools using the APT | |
114 | library. Several "front-end" interfaces exist, such as &dselect;, | |
115 | &aptitude;, &synaptic; and &wajig;.</para> | |
116 | ||
117 | <para>Unless the <option>-h</option>, or <option>--help</option> option is given, one of the | |
118 | commands below must be present.</para> | |
119 | ||
120 | <variablelist> | |
121 | <varlistentry><term>update</term> | |
122 | <listitem><para><literal>update</literal> is used to resynchronize the package index files from | |
123 | their sources. The indexes of available packages are fetched from the | |
124 | location(s) specified in <filename>/etc/apt/sources.list</filename>. | |
125 | For example, when using a Debian archive, this command retrieves and | |
126 | scans the <filename>Packages.gz</filename> files, so that information about new | |
127 | and updated packages is available. An <literal>update</literal> should always be | |
128 | performed before an <literal>upgrade</literal> or <literal>dist-upgrade</literal>. Please | |
129 | be aware that the overall progress meter will be incorrect as the size | |
130 | of the package files cannot be known in advance.</para></listitem> | |
131 | </varlistentry> | |
132 | ||
133 | <varlistentry><term>upgrade</term> | |
134 | <listitem><para><literal>upgrade</literal> is used to install the newest versions of all packages | |
135 | currently installed on the system from the sources enumerated in | |
136 | <filename>/etc/apt/sources.list</filename>. Packages currently installed with | |
137 | new versions available are retrieved and upgraded; under no circumstances | |
138 | are currently installed packages removed, or packages not already installed | |
139 | retrieved and installed. New versions of currently installed packages that | |
140 | cannot be upgraded without changing the install status of another package | |
141 | will be left at their current version. An <literal>update</literal> must be | |
142 | performed first so that <command>apt-get</command> knows that new versions of packages are | |
143 | available.</para></listitem> | |
144 | </varlistentry> | |
145 | ||
146 | <varlistentry><term>dselect-upgrade</term> | |
147 | <listitem><para><literal>dselect-upgrade</literal> | |
148 | is used in conjunction with the traditional Debian packaging | |
149 | front-end, &dselect;. <literal>dselect-upgrade</literal> | |
150 | follows the changes made by &dselect; to the <literal>Status</literal> | |
151 | field of available packages, and performs the actions necessary to realize | |
152 | that state (for instance, the removal of old and the installation of new | |
153 | packages).</para></listitem> | |
154 | </varlistentry> | |
155 | ||
156 | <varlistentry><term>dist-upgrade</term> | |
157 | <listitem><para><literal>dist-upgrade</literal> in addition to performing the function of | |
158 | <literal>upgrade</literal>, also intelligently handles changing dependencies | |
159 | with new versions of packages; <command>apt-get</command> has a "smart" conflict | |
160 | resolution system, and it will attempt to upgrade the most important | |
161 | packages at the expense of less important ones if necessary. | |
162 | So, <literal>dist-upgrade</literal> command may remove some packages. | |
163 | The <filename>/etc/apt/sources.list</filename> file contains a list of locations | |
164 | from which to retrieve desired package files. | |
165 | See also &apt-preferences; for a mechanism for | |
166 | overriding the general settings for individual packages.</para></listitem> | |
167 | </varlistentry> | |
168 | ||
169 | <varlistentry><term>install</term> | |
170 | <listitem> | |
171 | <para><literal>install</literal> is followed by one or more | |
172 | packages desired for installation or upgrading. | |
173 | Each package is a package name, not a fully qualified | |
174 | filename (for instance, in a Debian GNU/Linux system, | |
175 | libc6 would be the argument provided, not | |
176 | <literal>libc6_1.9.6-2.deb</literal>). All packages required | |
177 | by the package(s) specified for installation will also | |
178 | be retrieved and installed. | |
179 | The <filename>/etc/apt/sources.list</filename> file is | |
180 | used to locate the desired packages. If a hyphen is | |
181 | appended to the package name (with no intervening space), | |
182 | the identified package will be removed if it is installed. | |
183 | Similarly a plus sign can be used to designate a | |
184 | package to install. These latter features may be used | |
185 | to override decisions made by apt-get's conflict | |
186 | resolution system. | |
187 | </para> | |
188 | ||
189 | <para>A specific version of a package can be selected for installation by | |
190 | following the package name with an equals and the version of the package | |
191 | to select. This will cause that version to be located and selected for | |
192 | install. Alternatively a specific distribution can be selected by | |
193 | following the package name with a slash and the version of the | |
194 | distribution or the Archive name (stable, testing, unstable).</para> | |
195 | ||
196 | <para>Both of the version selection mechanisms can downgrade packages and must | |
197 | be used with care.</para> | |
198 | ||
199 | <para>This is also the target to use if you want to upgrade one or | |
200 | more already-installed packages without upgrading every package | |
201 | you have on your system. Unlike the "upgrade" target, which | |
202 | installs the newest version of all currently installed packages, | |
203 | "install" will install the newest version of only the package(s) | |
204 | specified. Simply provide the name of the package(s) you wish | |
205 | to upgrade, and if a newer version is available, it (and its | |
206 | dependencies, as described above) will be downloaded and | |
207 | installed. | |
208 | </para> | |
209 | ||
210 | <para>Finally, the &apt-preferences; mechanism allows you to | |
211 | create an alternative installation policy for | |
212 | individual packages.</para> | |
213 | ||
214 | <para>If no package matches the given expression and the expression contains one | |
215 | of '.', '?' or '*' then it is assumed to be a POSIX regular expression, | |
216 | and it is applied | |
217 | to all package names in the database. Any matches are then installed (or | |
218 | removed). Note that matching is done by substring so 'lo.*' matches 'how-lo' | |
219 | and 'lowest'. If this is undesired, anchor the regular expression | |
220 | with a '^' or '$' character, or create a more specific regular expression.</para></listitem> | |
221 | </varlistentry> | |
222 | ||
223 | <varlistentry><term>remove</term> | |
224 | <listitem><para><literal>remove</literal> is identical to <literal>install</literal> except that packages are | |
225 | removed instead of installed. Note the removing a package leaves its | |
226 | configuration files in system. If a plus sign is appended to the package | |
227 | name (with no intervening space), the identified package will be | |
228 | installed instead of removed.</para></listitem> | |
229 | </varlistentry> | |
230 | ||
231 | <varlistentry><term>purge</term> | |
232 | <listitem><para><literal>purge</literal> is identical to <literal>remove</literal> except that packages are | |
233 | removed and purged (any configuration files are deleted too).</para></listitem> | |
234 | </varlistentry> | |
235 | ||
236 | <varlistentry><term>source</term> | |
237 | <listitem><para><literal>source</literal> causes <command>apt-get</command> to fetch source packages. APT | |
238 | will examine the available packages to decide which source package to | |
239 | fetch. It will then find and download into the current directory the | |
240 | newest available version of that source package while respect the | |
241 | default release, set with the option <literal>APT::Default-Release</literal>, | |
242 | the <option>-t</option> option or per package with the | |
243 | <literal>pkg/release</literal> syntax, if possible.</para> | |
244 | ||
245 | <para>Source packages are tracked separately | |
246 | from binary packages via <literal>deb-src</literal> type lines | |
247 | in the &sources-list; file. This means that you will need to add such a line | |
248 | for each repository you want to get sources from. If you don't do this | |
249 | you will properly get another (newer, older or none) source version than | |
250 | the one you have installed or could install.</para> | |
251 | ||
252 | <para>If the <option>--compile</option> option is specified | |
253 | then the package will be compiled to a binary .deb using | |
254 | <command>dpkg-buildpackage</command>, if <option>--download-only</option> | |
255 | is specified then the source package will not be unpacked.</para> | |
256 | ||
257 | <para>A specific source version can be retrieved by postfixing the source name | |
258 | with an equals and then the version to fetch, similar to the mechanism | |
259 | used for the package files. This enables exact matching of the source | |
260 | package name and version, implicitly enabling the | |
261 | <literal>APT::Get::Only-Source</literal> option.</para> | |
262 | ||
263 | <para>Note that source packages are not tracked like binary packages, they | |
264 | exist only in the current directory and are similar to downloading source | |
265 | tar balls.</para></listitem> | |

268 | <varlistentry><term>build-dep</term> | |

270 | attempt to satisfy the build dependencies for a source package.</para></listitem> | |

273 | <varlistentry><term>check</term> | |

275 | for broken dependencies.</para></listitem> | |

277 | ||
278 | <varlistentry><term>clean</term> | |
279 | <listitem><para><literal>clean</literal> clears out the local repository of retrieved package | |
280 | files. It removes everything but the lock file from | |
281 | <filename>&cachedir;/archives/</filename> and | |
282 | <filename>&cachedir;/archives/partial/</filename>. When APT is used as a | |
283 | &dselect; method, <literal>clean</literal> is run automatically. | |
284 | Those who do not use dselect will likely want to run <literal>apt-get clean</literal> | |
285 | from time to time to free up disk space.</para></listitem> | |
286 | </varlistentry> | |
287 | ||
288 | <varlistentry><term>autoclean</term> | |
289 | <listitem><para>Like <literal>clean</literal>, <literal>autoclean</literal> clears out the local | |
290 | repository of retrieved package files. The difference is that it only | |
291 | removes package files that can no longer be downloaded, and are largely | |
292 | useless. This allows a cache to be maintained over a long period without | |
293 | it growing out of control. The configuration option | |
294 | <literal>APT::Clean-Installed</literal> will prevent installed packages from being | |
295 | erased if it is set to off.</para></listitem> | |
