Note on managing UID and GID for CNU/Linux users ① what a user can do depends on UID and GID. ② file permissions involve three types of users: ● owner ● group ● other ③ manage three User Files: ●/etc/passwd: there are 7 fields, and UID No. 4 is the GID, which can be accessed by any user ●/etc/shadow: there are nine fields, the password encrypted by the corresponding user in the passwd file is saved, and only the root user has the right to view ●/etc/g

Details about managing user permissions in VueJS applications and vuejs User Permissions In front-end applications that require authentication, we often want to use user roles to determine what content is visible. For example, visitors can read articles, but only registered users or administrators can see the edit button. It may be a bit difficult to manage permissions on the front end. You may have written such code before: if (user.type === ADMIN ||

A method for managing C ++ synchronization locks In C ++, constructor and destructor are provided to obtain and release processing resources. Through this mechanism of C ++, we can easily deal with the locking synchronization mechanism in C ++. Use the lock object as a member of the guard object (m_lock), and then Lock m_lock in the structure of the guard object: m_lock.acquire (), which is resolved in the destructor of the guard object. Lock: m_lock.

of a solution: you need to use STD::REF to wrap the number of references. A more thread creation form is required:Std::thread T (update_data_for_widget,w,std::ref (data));Assuming that you are familiar with Std::bind, the syntax of the pass is easy to understand.Since the Std::thread constructors and Std::bind are all using the same principle. This means that you can pass a pointer to a member function as a function parameter if you use the object pointer as the first parameter.Class X{public:v

change password: Provides a new command to add User newusers, which can be used to quickly and easily batch add users; When you can read the user name and plaintext password from a text file, Use this information to update a number of existing user groups or to create new users. One of the commands is CHPASSWD, which reads a file consisting of a user name and password from a standard input device and uses that information to update the existing user group.Note: To understand these two commands,
