本设计的目的是通过设计和调试一个简单的文件系统,主要是模拟文件操作命令的执行,来模拟文件管理,使学生对主要文件操作命令的实质和执行过程有比较深入的了解,掌握它们的基本实施方法。具体要求如下:
(1) 设计一个支持n个用户的文件系统,每个用户可拥有多个文件:
(2) 采用二级或二级以上的多级文件目录管理;
(3) 对文件应设置存去控制保护方式,如“只能执行”、“允许读”、“允许写等”;
(4) 系统的外部特征应接近于真实系统,可设置下述文件操作命令:
命 令 功 能 命 令 功 能
Create 建立文件 Read 读文件
Open 打开文件 Write 写文件
Close 关闭文件 Copy 复制文件
Delete 撤消文件 Directory 查询目录
(5) 通过键盘使用该文件系统,系统应显示操作命令的执行结果。-the purpose of this design is by designing and debugging a simple file system, main operation is simulated documents the execution of the order to simulate document management, enable students to the main document commands the substance and the implementation process of a more in-depth understanding, They grasp of the basic method. Specific requirements are as follows : (1) design a support n user file system, each user can have multiple files : (2) use of two or more than two multi-level directory management; (3) the document should be set up to deposit control and protection methods, such as "the only
