要完成的任务是模拟unix操作系统中的文件系统功能。在终端界面上用户可以象unix的shell命令一样输入一些命令，如输入ls 显示文件目录，chmod改变文件权限，chown改变文件拥有者，chgrp改变文件所属组，chnam改变文件名，pwd显示当前目录，cd改变当前目录，mkdir创建目录，rmdir删除目录，mk创建文件 ,cp文件拷贝，rm删除文件，cat显示文件内容，login切换用户，passwd修改用户口令 等功能。在后台，要实现混合索引式文件结构，包括用空闲结点号栈管理空闲结点和成组链接发管理空闲盘块。-courses on operating system design to complete the task of simulation unix operating system of file system function.
