paccheck [options] [packages...]

paccheck verifies the integrity and consistency of installed packages on Arch-based systems. It can check dependency relationships, verify that package files exist on disk, and validate file checksums against the package database records.
The tool is useful for detecting system corruption, identifying manually modified configuration files, finding missing files, and ensuring all package dependencies are properly satisfied. It reads package metadata from the local pacman database.

Checksum verification requires MTREE data to be present in packages (not all packages include this). Some modified files are expected (configuration files edited by user). Running with all verification options can be slow on systems with many packages.

Part of pacutils, a collection of utilities for pacman developed by Andrew Gregory. Provides functionality similar to rpm -V for RPM-based systems, allowing administrators to verify package integrity on Arch Linux.
