Abstract

A system (100) for CLI command processing is usable for configuring and administering electronic devices. The system includes: an I/O controlling module (110) for receiving input commands from a console or a terminal; a command parsing module (120) for parsing each character in the input commands, and separating the input commands into a job parent command and plural job child commands; a job controlling module (130) for executing the job parent command and job child commands; and a mode controlling module (140) for selecting an appropriate mode for inputting of commands by a user. The job controlling module comprises a job list (131), which stores the command information structures of the job parent command and job child commands. A related method is also provided.

Claims

1. A system for CLI (Command Line Interface) command processing, the system being usable for configuring and administering electronic devices, the system comprising:

an I/O (input/output) controlling module, for receiving input commands from a console or terminal;

a command parsing module, for parsing each character in the input commands, and separating the input commands into a job parent command and plural job child commands;

a job controlling module, for carrying out the job parent command and job child commands; and

a mode controlling module, for selecting an appropriate mode for inputting of commands by a user.

3. The system for CLI command processing as recited in claim 1, wherein the job controlling module comprises a tree format job list for storing the command information structures of the job parent command and the job child commands.

4. The system for CLI command processing as recited in claim 1, wherein the mode controlling module supports an execute mode, a privilege mode, a global configure mode, a DHCP (Dynamic Host Configuration Protocol) pool configure mode, and an interface configure mode.

5. The system for CLI command processing as recited in claim 4, wherein access to each of said modes is controlled by a respective password.

2. The system for CLI command processing as recited in claim 2, wherein the command parsing module builds up command information structures for the job parent command and the job child commands.

6. A method of CLI command processing, the method being usable for configuring and administering electronic devices, the method comprising the following steps:

receiving input commands from a console or terminal, and transmitting the input commands to a command parsing module;

checking whether there are special characters in the input commands;

separating the input commands into a job parent command and plural job child commands, and building up command information structures;

checking whether all the command information structures are valid;

transmitting the valid command information structures to a job controlling module, if all the command information structures are valid; and

executing tasks indicated by the valid command information structures.

7. The method of CLI command processing as recited in claim 6, further comprising the following step:

assigning meanings to the special characters and then performing step (c), if the input commands include special characters.

8. The method of CLI command processing as recited in claim 6, further comprising the following step:

showing an error to one or more users, if there is any invalid command information structure.

9. The method of CLI command processing as recited in claim 6, wherein step (f) comprises the following steps:

(f1) receiving and storing the valid command information structures;

(f2) executing each of the valid command information structures, and building up a main process and plural child processes; and

(f3) making the main process check and control the child processes.

10. The method of CLI command processing as recited in claim 9, wherein step (f3) comprises the following steps:

(f31) checking whether a child process has exited;

(f32) transmitting a result of the child process to a next child process, and executing the next child process, if the child process has exited;

(f33) checking whether all of child processes have exited; and

(f34) showing one or more results to said users, if all of the child processes have exited.

11. The method of CLI command processing as recited in claim 10, further comprising the following step:

waiting for the child process to exit, if the child process has not exited.

12. The method of CLI command processing as recited in claim 10, further comprising the following step:

returning to step (f31) in respect of another child process, if there is any child process that has not exited.

13. A method of command line interface (CLI) command processing to configure and administer electronic devices, comprising the following steps:

acquiring input commands from a user via said CLI;

parsing said input commands into a plurality of electronic-device recognizable job commands and command information structures;

creating process check information based on said command information structures; and

executing said job commands and command information structures under a process check based on said process check information.

14. The method as recited in claim 13, further comprising the step of selecting working modes of said CLI command processing on an access-controlled basis.
