Command
grep -E "installed|upgraded|removed" /var/log/pacman.log
Purpose
Shows which packages were installed, upgraded, or removed.
When To Use
Use this after a system update or when debugging a broken system to see what changed.
Workflow Role
Audit step after a system upgrade or before troubleshooting.
Logic
Reads /var/log/pacman.log and filters only package action entries.
Automation (Optional)
grep -E "installed|upgraded|removed" /var/log/pacman.log | tail -n 20
Single Example
You run a full system update, something breaks, and you check the last 20 package actions to identify the likely cause.
Quick Note
pacman.log grows over time, so filtering or limiting output keeps it readable.
