'-dlog' parameter

The -dlog parameter is available for all commands except the "help" command. Adding this parameter to a command is equivalent to running set -dlog true or set -dlog 1 except that the parameter included in the command overrides the global setting configured by set -dlog false and set -dlog 0.

Note The reason why you may use the -dlog parameter instead of -log is that the -log parameter itself is a valid parameter of Service Manager.
