4.4.4. Summary

This chapter covers the rpm command options to query the RPM database and RPM package files. You can determine the packages installed on your system, as well as which packages are responsible for the files on your system.
The RPM database maintains a lot of information about the files and packages on your system. Thus, it is crucial for managing your Linux systems. You should back up the RPM database before and after any installation, upgrade, or removal of packages.
You can also use the --rebuilddb option to the rpm command to rebuild a damaged RPM database.
