DESCRIPTION
CLI is a Jakarta Commons component that is used to make command line interrogation easier by providing a singular interface. This component helps in parsing these arguments provided via the command line, looking for missing and incorrect options and providing feedback to the end-user. These options are then fed to the application where they can be used for configuration or management.
This module provides a detailed look at the process of command line interrogation using the CLI component for examples. The format of CLI options is explained in great detail and all the possible types of CLI options are examined. These include, simple options, arguments, switch and property options. Finally, examples are provided that show how to format help messages for the end-user.
