On Linux, opens a console where messages are displayed.
dbmlsync -ux...
When -ux is specified, dbmlsync must be able to find a usable display. If it cannot find one, for example because the DISPLAY environment variable is not set or because the X window server is not running, dbmlsync fails to start.
To run the console in quiet mode, use -q.
On Windows, the console appears automatically.
