Investigating Packages with RPM

The Red Hat Package Manager (RPM) handles the backend operation for the high-level package manager DNF. Although DNF provides all the functionality of RPM and more, you can still use RPM to gain information about software packages. In this hands-on lab, you will be tasked with querying and verifying RPM packages using the `rpm` command. *This lab is not approved or sponsored by Red Hat.*
