Somewhere on the web, there was a great command line string that parsed your dpkg logs and presented a clean output to show you when you installed and removed various packages. I'm talking more than
dpkg --get-selections > installed_pkgs
rather, this command had a for loop to grab all the dpkg logs, and then used awk to find the important lines and then rewrite the output.
Anyone know a command that creates a list of installed and removed packages in Ubuntu?
