Paketler hakkında bilgi toplamak için APT sisteminin üzerinde çalışan programlar bulunmaktadır.
Fakat burada amacımız APT ile aynı bilgilere nasıl erişebileceğinizi sizlere anlatmaktır. Mesela, kurmak istediğiniz programın paket adını nasıl öğrenebiliriz?
That's what this chapter intends to answer. Let's check out our options.
Örneğin, eski iyi günleri hatırladınız, Atari 2600 günlerinizi... Ve bir Atari emülator programı kurmak için APT'yi kullanmak istiyorsunuz ancak kurmanız gereken paketin ismini bilmiyorsunuz. Yapmanız gereken:
$ aptitude search atari p atari-fdisk-cross - Partition editor for Atari (running on no p atari800 - Atari emulator for X/curses/SDL p console-keymaps-atari - Keymaps for Atari keyboards.
We find several packages related to what we're looking for, together with brief descriptions. The p letter at the begining of the line is similar to the notation used inside the curses UI aptitude uses. It means, thus, that the package is not installed. Important to notice that aptitude only searches package names by default. You can use all the search options provided by aptitude, which you can discover by reading the aptitude's User Manual. To search the descriptions, for example, you could use:
$ aptitude search ~datari p aranym - Atari Running on Any Machine p atari-fdisk-cross - Partition editor for Atari (running on no p atari800 - Atari emulator for X/curses/SDL p circuslinux - The clowns are trying to pop balloons to p circuslinux-data - Data files for circuslinux p console-keymaps-atari - Keymaps for Atari keyboards. [...] p stella - Atari 2600 Emulator for SDL & X windows [...]
Now, that returned many more packages, as we can see. Now that we found a list of possible solutions to our problem, let's go deeper into them:
$ aptitude show stella Package: atari-fdisk-cross Version: 0.7.1-5 Priority: extra Section: otherosfs Maintainer: Roman Hodek <roman@hodek.net$gt; Uncompressed Size: 106k Description: Partition editor for Atari (running on non-Atari) Atari-fdisk allows you to create and edit the partition table of a disk partitioned in Atari format. It supports both the AHDI 5.0 and ICD variations of the Atari format. It is an interactive tool with a menu similar to PC fdisk, and also supports most options of PC fdisk.
In this output you have many details about the package that you want (or don't
want) to install, together with the full description of the package. You can
also use the apt-cache
program to get informations like those. If
you choose this tool, it will be able to show multiple versions of a package
that are available, for example:
$ apt-cache show muine Package: muine Version: 0.5.0-1 Priority: optional Section: gnome Maintainer: Link Dupont <link@subpop.net> Depends: gstreamer-gconf (>= 0.6.4), libatk1.0-0 (>= 1.4.1), libbonobo2-0 (>= 2.4.3), libc6 (>= 2.3.2.ds1-4), libflac4, libgconf2-4 (>= 2.4.0.1), libgdbm3, libglib2.0-0 (>= 2.2.3), libgnomevfs2-0 (>= 2.4.1), libgnomevfs2-common (>= 2.4.1), libgstreamer0.6-0 (>= 0.6.1-2), libgtk2.0-0 (>= 2.2.1), libid3tag0 (>= 0.15.0b), libogg0 (>= 1.1.0), liborbit2 (>= 1:2.8.0), libpango1.0-0 (>= 1.2.1), libvorbis0a (>= 1.0.1), libvorbisfile3 (>= 1.0.1), libxml2 (>= 2.6.7), zlib1g (>= 1:1.2.1), gconf2 (>= 2.4.0), mono-jit (>= 0.30) | cli-virtual-machine, gtk-sharp (>= 0.17), gconf-sharp (>= 0.17), gnome-sharp (>= 0.17) Architecture: i386 Filename: ./pool/main/m/muine/muine_0.5.0-1_i386.deb Size: 164314 Installed-Size: 692 MD5sum: 9885f13e5ef4f76b3bf6fe7bb3ea8634 Description: Simple music player Muine is an innovative music player.

In summary, we have a range of weapons we can use to find out the name of a package we want.
Paket adını bulmada diğer bir yöntem de o paket tarafından kullanıldığını bildiğiniz bir dosyadan hareket etmektir. Örneğin belirli bir ".h" dosyasını içerdiğini bildiğiniz paketin ismini aşağıdaki gibi bulabilirsiniz:
# dpkg -S stdio.h libc6-dev: /usr/include/stdio.h libc6-dev: /usr/include/bits/stdio.h perl: /usr/lib/perl/5.6.0/CORE/nostdio.h
veya:
$ dpkg -S /usr/include/stdio.h libc6-dev: /usr/include/stdio.h
Notice that this method only works to find package names of packages that are
installed in your system. You'll have to use auto-apt
(see Programları anında kurma, Kısım 7.1) or
apt-file
(see Bir dosyanın hangi pakete ait
olduğunu bulma, Kısım 6.3) to search for files on packages which are not
installed. You can also take a look at the http://packages.debian.org/
website. To list the names of packages installed on your system, which is
useful, for example, if you plan to clean up your hard drive, you can run:
# dpkg -l | grep mozilla ii mozilla-browse 0.9.6-7 Mozilla Web Browser
Bu komut paket isimlerini belirli bir uzunluktan sonra kesmektedir. Yukarıdaki örnekte paketin tam ismi mozilla-browser'dır. Bu problemi gidermek için COLUMNS çevresel değişkenini aşağıdaki gibi ayarlamalısınız:
[kov]@[couve] $ COLUMNS=132 dpkg -l | grep mozilla ii mozilla-browser 0.9.6-7 Mozilla Web Browser - core and browser
If you want to install a package, and you can't find out what it is called by
searching with apt-cache
, but know the filename of the program
itself, or some other filename that belongs to the package, then you can use
apt-file
, which is included in the package of same name to find
the package name. This is done like this:
$ apt-file search dosya_adı
Bu komut aynı dpkg -S gibi çalışır ancak ayrıca verdiğiniz dosyayı içermesine rağmen sisteminizden sonradan kaldırılmış olan paketleri de listeler.
Bir paketin içeriğini aşağıdaki komutla listeleyebilirsiniz:
$ apt-file list paket_adı
apt-file
tüm paketler hakkında içerdikleri dosyalara ilişkin
kayıtları tutar. Aynı auto-apt'de olduğu gibi bu veritabanının da zamanla
güncellenmesi gereklidir:
# apt-file update
Öntanımlı olarak apt-file
auto-apt
ile aynı kaynağı
kullanır, bkz. Programları anında

There are lots of web resources with informations about the packages available in the Debian distribution, most of them directed mainly towards Debian Developers, but many of them may be useful for users, too.
The Debian Packages
Pages
lets you search for packages that are available on the various
architectures Debian supports and, also, search for the contents of all the
Debian packages. There are information regarding dependencies and other
relationships with packages. There are also links to download the source
package and the binary package for all architectures. You can use a shortcut
like http://packages.debian.org/packagename to have
quick access links to a package.
The Package Tracking
System
provides information about what happened to the package
recently, what are the TODO itens, from a Debian maintainers point of view,
provides a summary of bugs reported and some more very useful information. One
of the nice things about the Package Tracking System is that it lets you
"subscribe" to a package to follow all the emails that the maintainer
usually receives about the package. This way you can follow the development of
packages that are crucial for your work or play. The
http://packages.qa.debian.org/packagename shortcut
works here, as well.
Finally, the Bug Tracking
System
provides information about known bugs in the packages
distributed by Debian. This may be useful for you to find out why something
does not work the way you expected and even find solutions or work-arounds
through the bug logs. Also, read these pages and its documentation to be able
to fill good bug reports for Debian. The
http://bugs.debian.org/packagename shortcut also works
here, as expected, but the BTS (Bug Tracking System) also accepts other very
useful shortcuts like, for example,
http://bugs.debian.org/src:packagename to show all bug
reports on all binary packages provided by a given source package.
