CentOS: List the installed RPMs by date of installation/update?

Question

I'm on a CentOS 4 machine. I updated and installed some packages a few weeks back, but I don't remember the name of every package or the names of every dependency. I used yum.

Can I list the packages on my system by the date they were last installed or updated?

Answer 1

This should work on any RPM based machine:

rpm -qa --qf '%{INSTALLTIME} (%{INSTALLTIME:date}): %{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n' | sort -n

(To get a list of all possible tags, use rpm --querytags.)
