The YUM package manager cheat-sheet

We’ll cover more than a 100 commands of the yum package manager. Which is super handy to the system-administrators in order to be able to manage the packages in Linux distros that use yum, such as redhat 6 & 7, CentOS 6 & 7 and Scientific Linux 6 & 7.

Keep in mind that a root‘s privileges are needed. To gain those privileges, either login as root with su if you have the root‘s password, or prefix each of the following command with sudo if your user is a sudoer.
