How to use YUM to install and uninstall packages
 

Introduction

To update the system applying the most recent corrective patches of security and to the operating system is not as difficult as many do not suppose, nor either must be a hell of dependencies between packages RPM as some others argue. The reality of the things is that it is much very simple and single requires of good bandwidth or very many patience. Next we presented/displayed the procedures to use yum and to make easily what some denominate "horrible, difficult and complicated ".

Please note there are some changes that apply to Fedora Core 3. You will need to install GPG Key for yum in FC3.

Creating Yum Repo's For FC3.

To update system. Update of the system with all the dependencies that are necessary:

Cleaning of the system.

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:
Group install
Dont forget the quotation marks for group install.

I hope this will help you understand how to use yum more effeciently. I did this for our newbies that may want to uninstall packages which is not mention in the fedora FAQ. For more info on yum go here: http://www.fedorafaq.org/#installsoftware

Great howto.
One tip, you can use also joker-signs as * or ? e.g.
will install gkrellm, gkrellm-plugins, gkrellm-misc-plugins etc.

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

Thanks for the tip. ;)

Here's more:

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.
Example
To get the name of the package containing a given file:
example:
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:
To enable a repository which is disabled in the configuration:
example
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.
To install such a group:
Example:
And to update a group

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

Thanks again for the add-ons. :)

YUM is a delicious treat indeed. I never knew it had so much to it. Thanks imdeemvp and foolish! :)

Whoever gave that recommendation to the effect that "here are the only three repositories that yout need to get all the good add-ons", please repeat it here. I didn't find it by searching the forum messages.

Thanx for the kind to share this information :-)
