Find and reinstall broken packages:

paccheck –list-broken –files –file-properties –db-files –require-mtree | pacrepairdb

pacrepairdb expects all of the packages being repaired to be cached. Cached packages that match the name and version of an installed package are assumed to be the same package. No attempt is made to validate cached packages. If a cache contains a package that does not match the installed package, but nonetheless has the same name and version, pacrepairdb will blindly install it, worsening any database problems.

pacrepairdb does not check for leftover orphaned files. It is the user’s responsibility locate and handle orphaned files.

pacrepairdb determines whether or not to read package names from stdin based on a naive check using isatty (3). If pacrepairdb is called in an environment, such as a shell function or script being used in a pipe, where stdin is not connected to a terminal but does not contain package names to repair, pacrepairdb should be called with stdin closed. For POSIX-compatible shells, this can be done with <&-.
