Yum leaves as result of its use heads and packages RPM stored in the interior of the directory located in the route /var/cache/yum/. Particularly the packages RPM that have settled can occupy much space and is by such reason agrees to eliminate them once no longer they have utility. Also it agrees to do the same with the old heads of packages that no longer are in the data base. In order to make the corresponding cleaning, the following thing can be executed:

MORE:

One tip, you can use also joker-signs as * or ? e.g.

Code:

yum install gkrellm*

will install gkrellm, gkrellm-plugins, gkrellm-misc-plugins etc.

And to install/remove you have to be root! Not for searching.

To search in package names only, use yum list. This differs from search in that it's much faster, as it will search package names only, while yum search will search all the package info, including package description.

Code:

yum list something

Example

Code:

yum list mozilla

To get the name of the package containing a given file:

Code:

yum provides filename

example:

Code:

yum provides /usr/bin/mozilla

Here's some new goodies in yum 2.2 (Fedora Core 3 and beyond)

To get a list of packages updated/added to any of your repositories recently:

Code:

yum list recent

To enable a repository which is disabled in the configuration:

Code:

yum --enablerepo=reponame install packagename

example

Code:

yum --enablerepo=dag install j2re

To list available software groups, such as GNOME desktop environment or X window system. This is also available in the Core 2 yum, but servers doesn't use this wonderful feature much.

Code:

yum grouplist

To install such a group:

Code:

yum groupinstall "groupname"

Example:

Code:

yum groupinstall "GNOME Desktop Environment"

And to update a group

Code:

yum groupupdate "GNOME Desktop Environment"

And remember folks, you can always use -y to say yes to everything, and -C to use the cache only.
