Command Line Parameters allow you to run components silently in the background using the CLI (Command Line Interface), and automate how the program behaves depending on the results obtained.
Spybot allows you to use various command line parameters. The availability depends on the Spybot edition you are using. To display the available list of parameters, open the Command Prompt as an administrator. You can then navigate to the Spybot program folder in the Command Prompt (as shown in the image), and run the /help command.
