paclog [options]

paclog filters and displays entries from the pacman log file (/var/log/pacman.log). It provides structured access to package management history, making it easy to see when packages were installed, upgraded, or removed.
Part of the pacutils collection, paclog can filter by package name, action type, date range, or severity level. This is useful for troubleshooting system issues by reviewing recent package changes or tracking the history of a specific package.
The --pkglist option reconstructs the current installed package list by replaying the log, useful for verification or recovery scenarios.
