earliest installed pkg time.

April 29, 2011

Recording this for posterity – in case I forget.

date +%F --date=@`rpm -qa --qf '%{installtime}\n' | sort -nr | tail -1`

    This is the oldest package, not the date the machine was installed, right?

    Another one which is useful is the latest installed package date — a good way to tell if the machine has been updated recently. It’s a trivial modification of the one liner you posted.

    That looks a bit hacky, here’s a command you might not know about:

    repoquery –installed -qa –qf ‘%{installtime:isodate}’ | sort -nr | tail -1
