The Yellowdog Updater, Modified (YUM) is a libre and open-source command-line package-management utility for computers running the GNU/Linux operating system using the RPM Package Manager. Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality.
1.1 What Yum Can Do. Yum consists of the yum client itself as well as a suite of tools and numerous plugins that modify the basic default behavior of the yum client. In addition, the createrepo command allows one to create a yum repository on any suitable server.Once a yum repository is prepared any client permitted to access the repository over the network can install, update, or remove one or more rpm-based packages from the repository.f this isn't enough, yum is the back end for a number of GUI tools that provide a user with instant visual access to the entire (rather enormous) range of packages available for any linux distribution that relies on it.
