    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:
    Code:
    yum update
    Searches. To make a search of some package or term in the data base in some of the formed deposits yum in the system:
    Code:
     yum search any-package
    Example:
    Code:
    yum search httpd
    I hope this will help you understand how to use yum more effeciently. Any erros in this how please notify me.
    Consultation of information. To consult the information contained in a package in individual:
    Code:
     yum info any-package
    Example:
    Code:
    yum info httpd
    Installation of packages. Installation of paquetería with automatic resolution of dependencies:
    Code:
     yum install any-package
    Example.
    Code:
    yum install gkrellm
    Uninstalling packages. Desinstalación of packages along with everything what it depends on these:
    Code:
    yum remove any-package
    Example.
    Code:
    yum remove gkrellm
    Listing Packages. The following thing will list all the packages available in the data base yum and that can settle:
    Code:
     available yum list|less
    The following thing will list all the packages installed in the system:
    Code:
     yum list installed|less
    The following thing will list all the packages installed in the system and that can (they must) be updated:
    Code:
     yum list updates|less
    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:
    Code:
     yum clean all
    Group install
    Code:
    yum groupinstall "groupname"
    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.
    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.

    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.
    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.

    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.
