Linux User Management And Permission Management
This experiment is conducted by using Alibaba Cloud ECS. In the experiment, ECS runs on Ubuntu 16.04, which is a free open-source GNU/Linux operating system. As one of mainstream operating systems on the market, Ubuntu is a nice choice for users who just begin to use Linux. This experiment illustrates the user management and file permission management functions of Linux. You can familiarize yourself with commonly used Linux commands and working principles during the experiment, laying a solid foundation for further understanding of Linux.
