Hello,

Here's another way. It requires the installation of apt-show-versions 
first, but works pretty good.

apt-show-versions > ~/versions.txt
sort ~/versions.txt > ~/sversions.txt
rm ~/versions.txt

This gives you an alphabetically sorted list of all of your packages, 
with their current version information. If you need to get the list of 
packages which need updating use the following.

apt-show-versions -u > ~/needsupdate.txt

If you would prefer a list sorted by date so you can tell what has been 
added recently give this a try.

cd /usr/share
find -maxdepth 1 -type d -printf '%f  %T+\n' | sort -s -t ' ' -k 2.1nr 
-k 2.6n -k 2.9n -k 2.12r -k 2.15 -k 2.18 > ~/datesort.txt

That wiill give you a package list with the most recently installed 
dates at the top of the file.
