For details on how to set up each function, see set (sets up the operating environment).
For example, to set up the log level, execute the dlnkmgr command's set operation with the -ellv parameter specified. When the confirmation message is displayed, enter y to execute, or n to cancel the command.
The following is an example of executing the command:
