  1. For packages management better is dselect. It can list, display status and choose packages for install/reinstall/uninstall.

  2. WOW!

    Thanks for this helpful post. Could not have come in handy at a better time. I am in the process of moving all of my projects and other stuff onto another computer. So this really helped me a lot.

    BTW: For those who may not know, adding a ” > /dir/filename.ext ” at the end of the command will output to a text file so that you may print out a hardcopy if needed. – Just thought a little bit more useful info will help.
