Rebuilding database indices from installed package headers

rpm {–initdb|–rebuilddb} [-v] [–dbpath DIRECTORY] [–root DIRECTORY]

Use –initdb to create a new database if one doesn’t already exist (existing database is not overwritten), use –rebuilddb to rebuild the
database indices from the installed package headers.

root@linux:/var/lib/rpm # rpm –rebuilddb

rpm doesn’t return any errors.

root@linux:/var/lib/rpm # rpm -qa | wc -l
