show apt-get history in Ubuntu / Debian

Sometimes you need some information about your apt-get install / upgrade / remove history. (for example if you destroyed your ROS-Install on your laptop).

By adding a little code snippet to your .bashrc you achieve a very useful tool.

Now running

brings you all install entries with timestamp and version information.  Note: instead of install ‘upgrade‘ and ‘remove‘ works too. ‘rollback‘ brings you version information you’ll might need for what I now call downgrade.
