读者-写者问题的读写操作限制（包括读者优先和写者优先） 写-写互斥：不能有两个写者同时进行写操作 读-写互斥：不能同时有一个线程在读，而另一个线程在写。 读-读允许：可以有一个或多个读者在读。-Readers- read and write operations to write the problem of constraints (including the readers of priority and writing preferred) Write- write mutually exclusive: You can not have two writers write the same time Read- Write mutually exclusive: You can not simultaneously reading a thread while another thread is writing. Reading- Reading allowed: You can have one or more readers to read.

写一个脚本文件checkuser,该脚本运行时带一个用户名作为参数，具体要求如下： 1)如果命令行格式不符合要求，应有错误提示信息； 2)在/etc/passwd文件中查找是否有该用户， 如有，则输出“Found in the /etc/passwd file.” 否则，输出“No such on our system” -Write a script file checkuser, the script run-time with a user name as a parameter, and specific requirements are as follows: 1) If the command-line format does not meet the requirements, there should be error message 2) in/etc/passwd file to check if there were any users, and if so, then the output " Found in the/etc/passwd file. " Otherwise, output" No such on our system "

本次实验的目的在于将nachos中的锁机制和条件变量的实现补充完整，并利用这些同步机制实现几个基础工具类。实验内容分三部分：实现锁机制和条件变量，并利用这些同步机制将实验一中所实现双向有序链表类修改成线程安全的；实现一个线程安全的表结构；实现一个大小受限的缓冲区（详细内容请看nachos-labs.pdf）。-the purpose of the experiment is to the nachos lock mechanism and conditions for the realization of supplementary variables integrity, Using these synchronization mechanism based tool for achieving several categories. Experiment three parts : achieving lock mechanism and variable conditions, Using these experimental synchronization mechanism as a bidirectional orderly objectlist revise the security thread; the realization of a security thread table structure; the realization of a limited size of the buffer zone (for details, please see nachos- labs.pdf).
