Feature request: check whether dropbox is up to date

[mrmeszaros]

Recently I installed dropbox via the nautilus-dropbox apt package, and with the provided command line interface.

I experienced, that dropbox update does download the latest version regardless of the currently installed version.
This means, if I run the command twice in a row, it will do a download twice.

I would like a method to check the current (online) available version.

For example, dropbox update would only update, if a newer version is available, or if a new --force flag was passed.

Maybe the version command would output an extra line like update available.

> dropbox version
Dropbox daemon version: 163.4.5456 (Update available)
Dropbox command-line interface version: 2019.02.14

Or a separate command, like dropbox check-update that would:

• output Up to date and return 0 if it is up-to-date and
• output Update available and return 1 if it is not.

These are ideas, should be revised to ensure the CLI is consistent with itself.
