34 | <refsect1><title>Description</title> |
35 | <para><command>apt-get</command> is the command-line tool for handling packages, and may be | |
36 | considered the user's "back-end" to other tools using the APT | |
4bca8520 | 37 | library. Several "front-end" interfaces exist, such as |
9233ef0d | 38 | &aptitude;, &synaptic; and &wajig;.</para> |

24f6490f AL |
45 | <listitem><para><literal>update</literal> is used to resynchronize the package index files from |
46 | their sources. The indexes of available packages are fetched from the | |
47 | location(s) specified in <filename>/etc/apt/sources.list</filename>. | |
48 | For example, when using a Debian archive, this command retrieves and | |
49 | scans the <filename>Packages.gz</filename> files, so that information about new | |
50 | and updated packages is available. An <literal>update</literal> should always be | |
51 | performed before an <literal>upgrade</literal> or <literal>dist-upgrade</literal>. Please | |
52 | be aware that the overall progress meter will be incorrect as the size | |
53 | of the package files cannot be known in advance.</para></listitem> | |

57 | <listitem><para><literal>upgrade</literal> is used to install the newest versions of all packages |
58 | currently installed on the system from the sources enumerated in | |
59 | <filename>/etc/apt/sources.list</filename>. Packages currently installed with | |
60 | new versions available are retrieved and upgraded; under no circumstances | |
61 | are currently installed packages removed, or packages not already installed | |
62 | retrieved and installed. New versions of currently installed packages that | |
63 | cannot be upgraded without changing the install status of another package | |
64 | will be left at their current version. An <literal>update</literal> must be | |
65 | performed first so that <command>apt-get</command> knows that new versions of packages are | |
66 | available.</para></listitem> | |

24f6490f AL |
70 | <listitem><para><literal>dist-upgrade</literal> in addition to performing the function of |
71 | <literal>upgrade</literal>, also intelligently handles changing dependencies | |
72 | with new versions of packages; <command>apt-get</command> has a "smart" conflict | |
73 | resolution system, and it will attempt to upgrade the most important | |
74 | packages at the expense of less important ones if necessary. | |
6c1965bd | 75 | The <literal>dist-upgrade</literal> command may therefore remove some packages. |
24f6490f AL |
76 | The <filename>/etc/apt/sources.list</filename> file contains a list of locations |
77 | from which to retrieve desired package files. | |
78 | See also &apt-preferences; for a mechanism for | |
79 | overriding the general settings for individual packages.</para></listitem> | |

2b0de496 | 93 | <listitem> |
a7b228bd EL |
94 | <para><literal>install</literal> is followed by one or more |
95 | packages desired for installation or upgrading. | |
96 | Each package is a package name, not a fully qualified | |
b176de3a | 97 | filename (for instance, in a Debian system, |
5583d414 DK |
98 | <package>apt-utils</package> would be the argument provided, not |
99 | <filename>apt-utils_&apt-product-version;_amd64.deb</filename>). All packages required | |
a7b228bd EL |
100 | by the package(s) specified for installation will also |
101 | be retrieved and installed. | |
102 | The <filename>/etc/apt/sources.list</filename> file is | |
103 | used to locate the desired packages. If a hyphen is | |
104 | appended to the package name (with no intervening space), | |
105 | the identified package will be removed if it is installed. | |
106 | Similarly a plus sign can be used to designate a | |
107 | package to install. These latter features may be used | |
108 | to override decisions made by apt-get's conflict | |
109 | resolution system. | |
110 | </para> | |
24f6490f AL |
111 | |
112 | <para>A specific version of a package can be selected for installation by | |
113 | following the package name with an equals and the version of the package | |
114 | to select. This will cause that version to be located and selected for | |
115 | install. Alternatively a specific distribution can be selected by | |
116 | following the package name with a slash and the version of the | |
117 | distribution or the Archive name (stable, testing, unstable).</para> | |
118 | ||
119 | <para>Both of the version selection mechanisms can downgrade packages and must | |
120 | be used with care.</para> | |
121 | ||
2b0de496 EL |
122 | <para>This is also the target to use if you want to upgrade one or |
123 | more already-installed packages without upgrading every package | |
124 | you have on your system. Unlike the "upgrade" target, which | |
125 | installs the newest version of all currently installed packages, | |
126 | "install" will install the newest version of only the package(s) | |
127 | specified. Simply provide the name of the package(s) you wish | |
128 | to upgrade, and if a newer version is available, it (and its | |
129 | dependencies, as described above) will be downloaded and | |
130 | installed. | |
131 | </para> | |
132 | ||
24f6490f AL |
133 | <para>Finally, the &apt-preferences; mechanism allows you to |
134 | create an alternative installation policy for | |
135 | individual packages.</para> | |
136 | ||
137 | <para>If no package matches the given expression and the expression contains one | |
138 | of '.', '?' or '*' then it is assumed to be a POSIX regular expression, | |
139 | and it is applied | |
140 | to all package names in the database. Any matches are then installed (or | |
141 | removed). Note that matching is done by substring so 'lo.*' matches 'how-lo' | |
142 | and 'lowest'. If this is undesired, anchor the regular expression | |
143 | with a '^' or '$' character, or create a more specific regular expression.</para></listitem> | |
