If you are going for a complete reinstall of OS and you need to get a list of packages you have at present, so that you can reinstall them after you have installed Linux from scratch, run the following:

sudo dpkg --get-selections | awk '{ ORS=" "; print $1; }' > packagelist.txt

This saves the everything to packagelist.txt. Mind blown!
