Brief introduction

Yum (Yellow dog Updater, Modified) is a Shell front-end package manager in Fedora and RedHat as well as in SUSE. Based on RPM package management, RPM packages can be downloaded and installed automatically from designated servers, dependencies can be automatically dealt with, and all dependent software packages can be installed at one time without tedious downloading and installation. Yum provides commands to find, install, and delete one, a group, or even all of the software packages, and the commands are concise and easy to remember.
