That new cursor means that you have entered an incomplete SQL command, so MySQL is waiting for you to complete it.
The problem might have to do with the contents of the file, or it might have to do with the syntax you're using. Try this: Don't specify the password on the command line. Just skip the password, and MySQL will ask you for it.
Code:
mysql -u username -p MyDatabase < /srv/www/mydomain.com/public_html/databaseBU.sql
The above command would look as if it's supplying "MyDatabase" as the password, but in fact it's not. Crazy MySQL command line
