Linux教学中进程之间通过特殊文件通信的解析

Analysis of process communication through special file in Linux teaching

进程是操作系统的核心内容,进程通信是协调操作系统中多个任务同时运行的主要手段。针对学生在学习Linux系统时,对进程之间为什么需要使用命名管道和套接字文件进行通信的疑惑,从进程通信过程中,需要针对不同用户进程进行不同权限操作的角度,介绍了Linux系统引入文件系统的授权机制,实现进程通信过程中针对不同用户进程的授权,提高不同用户进程之间通信的灵活性,帮助学生对命名管道和套接字文件进行深入理解与实际应用。

Process is the core content of operating system, and process communication is the main means of coordinating multiple simultaneous tasks in an operating system. In response to students’ doubts about why processes need to use named pipes and socket files to communicate with each other, the authorization mechanism for the file system of the Linux system is introduced from the perspective of process permission management. Authorization for different user processes during process communication is implemented to improve the flexibility of communication between different user processes. Therefore it will help students to have a deep understanding and practical application of named pipes and socket files.
