What Others Think

At least under dpkg-based systems, you could just look at the timestamps on files in the dpkg info directory: ls -ltr /var/lib/dpkg/info/*.list | head -n 1 or for the number of packages installed on each date: ls -l /var/lib/dpkg/info/*.list | awk '{print $6}' | sort -n | uniq -c | sort -n
