getting a list of potential package updates.

[Franki <franki@htmlfixit.com>]

Hi guys,

Is it possible via apt-get update/upgrade to get a list of all the 
packages that would be updated without actually updating anything?

I looked at the man page, but nothing stuck out to me.

any tips would be most appreciated as I have a need to update my machine 
without changing specific packages.

regards

Franki
