30 Web Command Line Applications

To make the configuration of product parameters easier and allow users to add custom functionalities conveniently, we have designed command-line parameter functionality for the product. You can achieve corresponding functionalities by inputting commands into the command-line tool on the web page. This chapter will detail these functionalities.
