rpm (from here)

These tools work together with dnf or yum. DNF handles dependency solving, finding files on the network, repository management, and so on. RPM handles the lower-level part of actually putting the files on the system.

In most cases as an end user, DNF is all you need to interact with. You might use RPM commands for lower-level troubleshooting, but in most cases DNF provides all the functionality in a more friendly manner.

list all rpm packages in a kind brutal manner (usually apply | grep “something” to find desired package)

rpm -qa
