3. What command can you use to rebuild the RPM database?

Solution :

use the --rebuilddb option to tell the rpm command to rebuild database.

rpm --rebuilddb

This command rebuilds the RPM database from the installed packages, the file named Packages in the /var/lib/rpm directory. Only the Packages file is required. All the other files can be recreated from the Packages file. If your database is OK, this command won't do much, other than shrink the size of your RPM database by removing unused entries. This command will take some time to execute.
