Stupid RPM query tricks
I was doing upgrades on my personal router, and didn’t remember when I installed the last set of RPMs. I found this site that shows how to use the querytags properly. I had managed to miss the man page entry on the queryformat parameter.
Anyway, to get the sorted list of RPMs, by install time:
rpm -qa –queryformat ‘%{NAME} %{INSTALLTIME}\n’ |sort -n +1
Time is in unix epoch notation. A handy page for converting it can be found here. Save me the bother of writing the perl.
