Research and design of multilayer command line parsing framework

Based on integrating commons CLI,a command line framework to solve the problem is presented that command line programs are not unified and not able to support multilayer command parsing in large network server.The concept of command manager is brought forward and command caller is used to separate the command processing strategy from command class,so it may make the logic of com-mand implementation simple.And then,the main structure and operations of the framework is introduced.At last,the compatibility,extensibility and flexibility of the framework are analysed.
