A source RPM (SRPM) can contain many separate rpm packages. The packages held within it do not necessarily relate to the name of their source rpm. It is important to know how to find the SRPM for a package.


There are several ways to find out.

Search among installed packages by name

If you have a package installed you can use the command
$ rpm -qi <package name>

For example:

$ rpm -qi firefox
Name        : firefox
Epoch       : 0
Version     : 10.0.4
Release     : 1.mga2
Architecture: i586
Install Date: Don 31 Mai 2012 00:41:53 CEST
Group       : Networking/WWW

License     : MPLv1+
Signature   : RSA/SHA1, Son 22 Apr 2012 11:45:08 CEST, Key ID b742fa8b80420f66
Source RPM  : firefox-10.0.4-1.mga2.src.rpm
Build Date  : Son 22 Apr 2012 11:28:47 CEST
Build Host  : jonund.mageia.org
Relocations : (not relocatable)
Packager    : tmb <tmb>
Vendor      : Mageia.Org
URL         : http://www.mozilla.com/firefox/
Summary     : Next generation web browser
Description :
The award-winning Web browser is now faster, more secure, and fully customizable
to your online life. With Firefox(R), we've added powerful new features that
make your online experience even better. It is an 'open source' product which is
freely available, and is acquiring a growing proportion of international web
browser usage.

Firefox claims to offer a more secure web browsing experience than other products,
with better protection against spyware and other Internet-based security threats.
It includes all the standard features of a modern web browser, like Internet
searching, tracking recently visited sites, setting up shortcuts to favourite
sites, customising the software behaviour and so on. Firefox also includes
features like 'tabbed browsing' (opening several web sites as sections within the
same window) and methods for controlling pop-up windows, cookies and downloaded
files.

This output shows you that the SRPM firefox-10.0.4-1.mga2.src.rpm is currently installed on your system.

Search among installed packages by path

If you wish to find out what provides a certain file on your system you can use the command
$ rpm -qif </path/to/filename.ext>

This is especially useful for unfamiliar files.

For example:

$ rpm -qif /usr/lib/libass.so.4
Name        : libass4                      Relocations: (not relocatable)

If you want to know the path to an application, use the $ which command which searches all directories in your path.

$ which firefox
/usr/bin/firefox

Alternatively you can use the command described above.

Search any package on all medias

This works whether you have the package installed or not:

$ urpmq -i <package name>
$urpmq -i kontact

Name        : kontact
Version     : 4.4.11.1
Release     : 2.1.mga1
Group       : Graphical desktop/KDE
Size        : 997979                       Architecture: i586
Source RPM  : kdepim4-4.4.11.1-2.1.mga1.src.rpm
URL         : http://pim.kde.org
Summary     : Kontact Container
Description :
The KDE Kontact Personal Information Management suite unites mature and
proven KDE applications under one roof. Thanks to the powerful KParts
technology, existing applications are seamlessly integrated into one.

In this example, "$ urpmq -i kontact" above shows the SRPM of kontact-4.4.11.1-2.1.mga1 to be kdepim4-4.4.11.1-2.1.mga1.src.rpm.

Note: "urpmq -i <package name>" will search on all medias enabled on your system and output all packages. So if there was already an update to a package, the output will look like this (provided you didn't disable Core Updates):

$ urpmq -i sudo
Name        : sudo
Version     : 1.8.3p2
Release     : 1.mga2
Group       : System/Base
Size        : 1785410                      Architecture: i586

On the other hand, if an update candidate is awaiting validation in Core Updates Testing and you have this media enabled on your system, the output may look like this:

$ urpmq -i thunderbird
Name        : thunderbird
Version     : 10.0.5
Release     : 1.mga2
Group       : Networking/Mail

Note: If you have several medias enabled, urpmq -i does not indicate where a package comes from. If this information matters to you, read on to find out how to search more effectively.

Search any package on a specific media

As mentioned above, "urpmq -i <package name>" searches a package on all medias enabled on your system. To limit the search to just one media, use

urpmq -i --media "<Core Release/Core Updates/Core Updates Testing>"

For the sake of clarity, the following examples are from the same system as the ones used in the #Search any package on all medias section.

$ urpmq -i --media "Core Release" sudo
Name        : sudo
Version     : 1.8.3p2
Release     : 1.mga2
Group       : System/Base

$ urpmq -i --media "Core Updates" sudo
Name        : sudo
