Parameters tell the CLI the specific details needed to perform an action. Some actions work without any additional details, but most require one or more parameters and accept additional optional parameters to perform the task.
The CLI requires at least one special parameter named action that tells what action to perform, without the action parameter, CLI displays help with some example actions. Parameters do not have prefixes like actions and are often specific to the app for the action.
For example, the action getServerInfo requires details about the app or server from where the information is retrieved. To obtain the required information, the server parameter is used.
The getServerInfo action also accepts optional parameters such as outputFormat, dateFormat, file, append, and encoding.
