Coursera 课程《Linux 系统管理轻松入门》是一门注重实际应用，旨在帮助初学者快速掌握 Linux 操作的课程。与许多枯燥的命令堆砌式教学不同，本课程将通过讲述命令背后的故事和逻辑，利用强大的叙事性神经记忆网络（narrative neural networks）记忆技巧，让学习者更轻松、更深入地理解和记住 Linux 命令。 课程强调 Linux 系统并非设计得复杂难懂，而是因为我们忽略了其命令命名的原始线索。通过理解每个命令的起源和上下文，学习者可以高效记忆并灵活运用。 本课程面向希望成为 Linux 用户或管理员的初学者，将涵盖 Linux 基础知识，包括： * **基本导航：** 学习如何在 Linux 文件系统中进行移动和探索。 * **诊断：** 掌握查看系统状态和进行基本故障排除的方法。 * **环境查看：** 了解如何查看和理解 Linux 运行环境。 课程以一个生动的例子——`nice` 命令——来展示其教学理念。“`nice`”命令用于调整进程的优先级，但许多人误用。课程解释，“`nice`”源自“好人最后”（Nice guys finish last）这句俗语。给进程设置 `nice` 值，实际上是让它“谦让”其他进程，因此 `nice +20`（更“nice”）意味着进程会运行得更慢。理解了这一背景故事，学习者就能牢牢记住 `nice` 命令的正确用法。 总之，这门课程以其生动有趣、注重记忆技巧的教学方式，让 Linux 学习过程不再乏味，真正实现 Linux 系统管理的轻松入门。
This is a practical course dedicated to real-world scenarios which will get you into Linux quickly, and not just fill your head with commands. Linux was not designed to be complicated or difficult or cryptic! If you know the context of why the commands are named the way they are, you will remember them easily!Do you ever wonder how people on television memorizing PI to 100 decimal places or the random order of an entire deck of playing cards? They use a technique which creates a narrative. Linux seems unfriendly and cryptic, but the system was never meant to be that way. In fact, the commands were supposed to be easy to remember but we have forgotten what the original clues were! I teach with this in mind and use memorization techniques based on narrative neural networks which are the strongest methods of memorization humans have. In this course for beginners who want to be users or administrators of Linux, I will show you how to do Linux basics which include basic navigation, diagnostics, and viewing the environment.For example, there is a command called NICE. Nice prioritizes processes or application on a computer to perform better or get preferential treatment. Most people use this command incorrectly. They tell the application to perform using NICE and it gets slower and more erratic. But they don't know the REASON.The reason is because nice was named after the saying "NICE GUYS FINISH LAST". When you nice a program, you are telling the program to be "nice" and let the other guys go ahead. In other words, nice +20 is "nicer", which means SLOWER. Now that you know the story, you will never forget the way to use the command nice!Every command has a history and context! Much less boring than typical courses!
