The Yellowdog Updater, Modified (YUM) is a libre and open-source command-line package-management utility for computers running the 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. YUM allows for automatic updates and package and dependency management on RPM-based distributions. Read more on Wikipedia...
