Description: 本软件模拟Shell 的命令解释程序，了解如何创建子进程来执行一项专门的工作以及父进程如何继续子进程的工作。编写一个C语言程序作为Linux内核的Shell命令行解释程序，所执行的结果需和系统命令方式保持一致。基本运行方式为：当用户敲入命令行如：identifier[identifier[identifier]]，Shell应该解析命令行参数指针数组argv[argc]。-The software simulation of the Shell command interpreter to understand how to create a child process to perform a specific job as well as the parent process on how to continue the work of sub-process. The preparation of a C language program as a Linux kernel Shell command line interpreter, the implementation of the results have to be ordered and systematic way to maintain consistency. Basic operation mode as follows: When a user input command line such as: identifier [identifier [identifier]], Shell command line parameters should resolve pointer array argv [argc]. Platform: |

Description: linux环境下，实现的shell解释器，实现功能主要有：
1. 基本界面由输入提示符开头
2. 执行可执行文件包括参数
3. 错误提示
4. 内置简单shell 命令
cd
exit
5. 单次I/O 重定向 > <
6. 单次管道 |
7. 后台运行 &
8. 顺序执行多个命令 ；-linux environment, to achieve the shell interpreter to realize functions are: 1 basic interface to the input prompt at the beginning 2. run the executable file, including parameters of 3 error 4 built-in simple shell command cd exit 5. Single I/O redirection> < 6 single pipe | 7. running in the background & 8 in order to execute multiple commands Platform: |
