Introduction
After the introduction in the previous lecture (Linux | 13. Concepts of Users and Groups), everyone should have a basic understanding of users and groups (Linux | 13. Concepts of Users and Groups) and be able to master the basic commands for user management (Linux | 14. User Management Commands (useradd, passwd, userdel, su)). In a server, not only users need to be managed, but various files also require hierarchical management to control different users’ read, write, and execute permissions on different files. This operation requires an administrator account. If you are using a shared server, you can perform the corresponding operations in the administrator account of the subsystem or virtual machine:Linux | Three. Free Linux System – WSLLinux | Four.

Please stop saying my links are invalid. I don’t know why Tencent and Baidu Cloud are not compatible; the WeChat page or Tencent browser often cannot open Baidu Cloud links. It’s best to open the links in Google Chrome. If they really become invalid, please remind customer service to change the link.
