Know which version dpkg/apt considers more recent
Compares two versions with dpkg. It is not always obvious what version dpkg/apt will consider to be more recent. Operators include the following : * These treat an empty version as earlier than any version: lt le eq ne ge gt. * These treat an empty version as later than any version: lt-nl le-nl ge-nl gt-nl. * These are provided only for compatibility with control file syntax: < > >. This command doesn't output anything. It only returns with status 0 or 1, hence the echo "y" || echo "n" to get an output.
