INSTALL, REMOVE AND UPGRADE PACKAGES WITH YUM CHEAT SHEET

If you are a developer, it's highly possible you will face situations where you need to install a new RPM package or update an existing one.

YUM has a lot of commands, but in this post, I'll focus on those commands that let us manage package installations or updates.

By default, Yum will automatically attempt to check all configured repositories to resolve all package dependencies during an installation or upgrade. The following is a list of the most commonly-used yum commands. For a complete list of available yum commands, refer to man yum.
