linux学生选课管理系统怎么定义学生帐号文件、教师帐号文件和课程文件。请给出具体代码

以下是一个简单的示例代码，用于创建学生帐号文件、教师帐号文件和课程文件：

# 创建学生帐号文件
touch student_accounts.txt
echo "Name,Student ID,Gender,Age,Class,Course,Grade" >> student_accounts.txt
echo "John,1001,Male,20,Class 1,Math,80" >> student_accounts.txt
echo "Kate,1002,Female,19,Class 2,English,90" >> student_accounts.txt

# 创建教师帐号文件
touch teacher_accounts.txt
echo "Name,Teacher ID,Gender,Age,Courses" >> teacher_accounts.txt
echo "Tom,2001,Male,35,Math" >> teacher_accounts.txt
echo "Lily,2002,Female,28,English" >> teacher_accounts.txt

# 创建课程文件
touch course_info.txt
echo "Course Name,Course ID,Teacher,Credits,Time,Location,Students,Grades" >> course_info.txt
echo "Math,001,Tom,3,Monday 8:00-10:00,Room 101,1001-80" >> course_info.txt
echo "English,002,Lily,2,Wednesday 14:00-16:00,Room 102,1002-90" >> course_info.txt

以上代码仅为示例，实际应用中需要根据具体需求进行修改和完善。同时，对于文件中的数据进行增删改查操作时，也需要编写相应的代码实现。
