Before running an --upgrade you may be interested to know the list of packages that need to be upgraded. The --upgrade-info command gives you that information.

The command also specifies whether the --upgrade-urgent command will have an effect on those packages. The idea is simple: if a package is marked as having a High or higher Urgency, then it should be upgraded as soon as possible. So running --upgrade-urgent is useful to ensure that your system remains secure.

With the --verbose flag you also get a list of packages that can be installed and the list of packages that are installed and up to date.
