I use kde.repo file with following content as example on this guide:

Basic Yum Commands and how to use them
Basic Yum Commands and how to use them
This is not an exhaustive list of all yum commands but it is a list of the basic/common/important ones. For a complete list see the yum man page.
yum list [available|installed|extras|updates|obsoletes|all|recent] [pkgspec]
This command lets you list packages in any repository enabled on your system or installed. It also lets you list specific types of packages as well as refine your list with a package specification of any of the package's name, arch, version, release, epoch.
yum list
By default 'yum list' without any options will list all packages in all the repositories and all the packages installed on your system. Note: 'yum list all' and 'yum list' give the same output.
yum list available
Lists all the packages available to be installed in any enabled repository on your system.
yum list installed
This is equivalent to rpm -qa. It lists all the packages installed on the system.
yum list extras
This command lists any installed package which no longer appears in any of your enabled repositories. Useful for finding packages which linger between upgrades or things installed not from a repo.
yum list obsoletes
This command lists any obsoleting relationships between any available package and any installed package.
yum list updates
This command lists any package in an enabled repository which is an update for any installed package.
yum list recent
This command lists any package added to any enabled repository in the last seven(7) days.
yum list pkgspec
This command allows you to refine your listing for particular packages.
Examples of pkgspecs:
yum list zsh yum list joe\* yum list \*.i386 yum list dovecot-1.0.15
yum install/remove/update
....
yum check-update
Exactly like yum list updates but returns an exit code of 100 if there are updates available. Handy for shell scripting.
yum grouplist
yum groupinfo
yum groupinstall
yum groupupdate
yum groupremove
Please see the YumGroups page on this wiki for information about the above commands.
yum info
This displays more information about any package installed or available. It takes the same arguments as yum list but it is best run with a specific package name or glob. Example:
$ yum info yum Installed Packages Name : yum Arch : noarch Version : 3.2.20 Release : 3.fc10 Size : 2.5 M Repo : installed Summary : RPM installer/updater URL : http://yum.baseurl.org/ License : GPLv2+ Description: Yum is a utility that can check for and automatically download and : install updated RPM packages. Dependencies are obtained and downloaded : automatically prompting the user as necessary.
yum search
This allows you to search for information from the various metadata available about packages. It can accept multiple arguments. It will output the packages which match the most terms first followed by the next highest number of matches, etc. Specifically yum search looks at the following fields: name, summary, description, url. If you're searching for what package provides a certain command try yum provides instead.
Search example:
$ yum search python rsync ssh ========================= Matched: python, rsync, ssh ========================== rdiff-backup.i386 : Convenient and transparent local/remote incremental : mirror/backup ============================ Matched: python, rsync ============================ cobbler.noarch : Boot server configurator ============================= Matched: python, ssh ============================= denyhosts.noarch : A script to help thwart ssh server attacks pexpect.noarch : Pure Python Expect-like module python-paramiko.noarch : A SSH2 protocol library for python python-twisted-conch.i386 : Twisted SSHv2 implementation ============================= Matched: rsync, ssh ============================== duplicity.i386 : Encrypted bandwidth-efficient backup using rsync algorithm pssh.noarch : Parallel SSH tools
yum provides/yum whatprovides
This command searches for which packages provide the requested dependency of file. This also takes wildcards for files. Examples:
$ yum provides MTA 2:postfix-2.5.5-1.fc10.i386 : Postfix Mail Transport Agent Matched from: Other : MTA exim-4.69-7.fc10.i386 : The exim mail transfer agent Matched from: Other : MTA sendmail-8.14.3-1.fc10.i386 : A widely used Mail Transport Agent (MTA) Matched from: Other : Provides-match: MTA $ yum provides \*bin/ls coreutils-6.12-17.fc10.i386 : The GNU core utilities: a set of tools commonly : used in shell scripts Matched from: Filename : /bin/ls
yum shell

yum makecache
Is used to download and make usable all the metadata for the currently enabled yum repos. This is useful if you want to make sure the cache is fully current with all metadata before continuing.
yum clean
During its normal use yum creates a cache of metadata and packages. This cache can take up a lot of space. The yum clean command allows you to clean up these files. All the files yum clean will act on are normally stored in /var/cache/yum.
Example commands and what they do:
yum clean packages
This cleans up any cached packages in any enabled repository cache directory.
yum clean metadata
This cleans up any xml metadata that may have been cached from any enabled repository.
yum clean dbcache
Yum will create or download some sqlite database files as part of its normal operation. This command clean up the cached copies of those from any enabled repository cache.
yum clean all
Clean all cached files from any enabled repository. Useful to run from time to time to make sure there is nothing using unnecessary space.
YUM Autocomplete on Fedora, CentOS, Red Hat
This is quick tip, howto use Bash auto complete (autocomplete) with YUM (example) on Fedora, CentOS, Red Hat (RHEL).
Autocomplete feature is familiar to many who have used the Debian based Linux, like Debian and Ubuntu. For some reason, this feature is not automatically activated/installed on Red Hat -based Linux distros, like Fedora, CentOS and Red Hat (RHEL). Actually auto completion works with any Bash programs, but I think it’s very useful example with YUM and also with RPM.
1. Install bash-completion
1.1 Change to root
1.2 Install bash-completion package with YUM
1.3 Logout console
Then logout console or close command line and log back in.
2. Autocomplete usage
[TAB] = press tab/tabulator
