 There are no required arguments. By default, the local database is checked
 using the default unix socket. You can force TCP on localhost by using an
 IP address or FQDN ('localhost' will use the socket as well).

Notes:
 You must specify -p with an empty string to force an empty password,
 overriding any my.cnf settings.
