56 | <refsect1><title>Description</title> | |
57 | <para><command>apt-get</command> is the command-line tool for handling packages, and may be | |
58 | considered the user's "back-end" to other tools using the APT | |
59 | library. Several "front-end" interfaces exist, such as dselect(8), | |
60 | aptitude, synaptic, gnome-apt and wajig.</para> | |
61 | ||
62 | <para>Unless the <option>-h</option>, or <option>--help</option> option is given, one of the | |
63 | commands below must be present.</para> | |
64 | ||
65 | <variablelist> | |
66 | <varlistentry><term>update</term> | |
67 | <listitem><para><literal>update</literal> is used to resynchronize the package index files from | |
68 | their sources. The indexes of available packages are fetched from the | |
69 | location(s) specified in <filename>/etc/apt/sources.list</filename>. | |
70 | For example, when using a Debian archive, this command retrieves and | |
71 | scans the <filename>Packages.gz</filename> files, so that information about new | |
72 | and updated packages is available. An <literal>update</literal> should always be | |
73 | performed before an <literal>upgrade</literal> or <literal>dist-upgrade</literal>. Please | |
74 | be aware that the overall progress meter will be incorrect as the size | |
75 | of the package files cannot be known in advance.</para></listitem> | |
76 | </varlistentry> | |
77 | ||
78 | <varlistentry><term>upgrade</term> | |
79 | <listitem><para><literal>upgrade</literal> is used to install the newest versions of all packages | |
80 | currently installed on the system from the sources enumerated in | |
81 | <filename>/etc/apt/sources.list</filename>. Packages currently installed with | |
82 | new versions available are retrieved and upgraded; under no circumstances | |
83 | are currently installed packages removed, or packages not already installed | |
84 | retrieved and installed. New versions of currently installed packages that | |
85 | cannot be upgraded without changing the install status of another package | |
86 | will be left at their current version. An <literal>update</literal> must be | |
87 | performed first so that <command>apt-get</command> knows that new versions of packages are | |
88 | available.</para></listitem> | |
89 | </varlistentry> | |

91 | <varlistentry><term>dselect-upgrade</term> | |
92 | <listitem><para><literal>dselect-upgrade</literal> | |
93 | is used in conjunction with the traditional Debian packaging | |
94 | front-end, &dselect;. <literal>dselect-upgrade</literal> | |
95 | follows the changes made by &dselect; to the <literal>Status</literal> | |
96 | field of available packages, and performs the actions necessary to realize | |
97 | that state (for instance, the removal of old and the installation of new | |
98 | packages).</para></listitem> | |
99 | </varlistentry> | |
100 | ||
101 | <varlistentry><term>dist-upgrade</term> | |
102 | <listitem><para><literal>dist-upgrade</literal> in addition to performing the function of | |
103 | <literal>upgrade</literal>, also intelligently handles changing dependencies | |
104 | with new versions of packages; <command>apt-get</command> has a "smart" conflict | |
105 | resolution system, and it will attempt to upgrade the most important | |
106 | packages at the expense of less important ones if necessary. | |
107 | The <filename>/etc/apt/sources.list</filename> file contains a list of locations | |
108 | from which to retrieve desired package files. | |
109 | See also &apt-preferences; for a mechanism for | |
110 | overriding the general settings for individual packages.</para></listitem> | |
111 | </varlistentry> | |
112 | ||
113 | <varlistentry><term>install</term> | |
114 | <listitem><para><literal>install</literal> is followed by one or more packages desired for | |
115 | installation. Each package is a package name, not a fully qualified | |
116 | filename (for instance, in a Debian GNU/Linux system, libc6 would be the | |
117 | argument provided, not <literal>libc6_1.9.6-2.deb</literal>) All packages required | |
118 | by the package(s) specified for installation will also be retrieved and | |
119 | installed. The <filename>/etc/apt/sources.list</filename> file is used to locate | |
120 | the desired packages. If a hyphen is appended to the package name (with | |
121 | no intervening space), the identified package will be removed if it is | |
122 | installed. Similarly a plus sign can be used to designate a package to | |
123 | install. These latter features may be used to override decisions made by | |
124 | apt-get's conflict resolution system.</para> | |
125 | ||
126 | <para>A specific version of a package can be selected for installation by | |
127 | following the package name with an equals and the version of the package | |
128 | to select. This will cause that version to be located and selected for | |
129 | install. Alternatively a specific distribution can be selected by | |
130 | following the package name with a slash and the version of the | |
131 | distribution or the Archive name (stable, testing, unstable).</para> | |
132 | ||
133 | <para>Both of the version selection mechanisms can downgrade packages and must | |
134 | be used with care.</para> | |
135 | ||
136 | <para>Finally, the &apt-preferences; mechanism allows you to | |
137 | create an alternative installation policy for | |
138 | individual packages.</para> | |
139 | ||
140 | <para>If no package matches the given expression and the expression contains one | |
141 | of '.', '?' or '*' then it is assumed to be a POSIX regular expression, | |
142 | and it is applied | |
143 | to all package names in the database. Any matches are then installed (or | |
144 | removed). Note that matching is done by substring so 'lo.*' matches 'how-lo' | |
145 | and 'lowest'. If this is undesired, anchor the regular expression | |
146 | with a '^' or '$' character, or create a more specific regular expression.</para></listitem> | |
147 | </varlistentry> | |

149 | <varlistentry><term>remove</term> | |
150 | <listitem><para><literal>remove</literal> is identical to <literal>install</literal> except that packages are | |
151 | removed instead of installed. If a plus sign is appended to the package | |
152 | name (with no intervening space), the identified package will be | |
153 | installed instead of removed.</para></listitem> | |

161 | <varlistentry><term>source</term> |
162 | <listitem><para><literal>source</literal> causes <command>apt-get</command> to fetch source packages. APT | |
163 | will examine the available packages to decide which source package to | |
164 | fetch. It will then find and download into the current directory the | |
165 | newest available version of that source package. Source packages are | |
166 | tracked separately from binary packages via <literal>deb-src</literal> type lines | |
167 | in the &sources-list; file. This probably will mean that you will not | |
168 | get the same source as the package you have installed or as you could | |
169 | install. If the --compile options is specified then the package will be | |
170 | compiled to a binary .deb using dpkg-buildpackage, if --download-only is | |
171 | specified then the source package will not be unpacked.</para> | |
172 | ||
173 | <para>A specific source version can be retrieved by postfixing the source name | |
174 | with an equals and then the version to fetch, similar to the mechanism | |
175 | used for the package files. This enables exact matching of the source | |
176 | package name and version, implicitly enabling the | |
177 | <literal>APT::Get::Only-Source</literal> option.</para> | |
178 | ||
179 | <para>Note that source packages are not tracked like binary packages, they | |
180 | exist only in the current directory and are similar to downloading source | |

198 | <filename>&cachedir;/archives/partial/</filename>. When APT is used as a | |
199 | &dselect; method, <literal>clean</literal> is run automatically. | |
200 | Those who do not use dselect will likely want to run <literal>apt-get clean</literal> | |

207 | removes package files that can no longer be downloaded, and are largely | |
208 | useless. This allows a cache to be maintained over a long period without | |
209 | it growing out of control. The configuration option | |
