If you can identify the relevant program in the command, you can find their
man pages and answer many of these questions quickly. In this case, you
have two programs working in each command and one option on the second
program in each. Sudo is the first. do-release-upgrade and apt-get are the
other two. So to find your answers from the command line, you can use the
"man" program to bring up the manual pages, or search for them on the web
by entering "man+program-name" into google.
From the command line:
>> man do-release-upgrade
>> man apt-get
From there you will probably read that do-release-upgrade will upgrade your
system to the newest version it can find. I think that is a program
specific to Ubuntu if I am not mistaken. apt-get dist-upgrade will read
from your /etc/sources file and will update all new packages, and where
necessary, install and/or remove old dependecies. apt-get dist-upgrade
should not change OS versions unless you specifically update your sources
to a new repository, if I remember right.
Hope that helps. Just so you know, I will probably not be available to
answer any follow up questions if you have them. Best~
