Linux User Management Deep Dive

Welcome to the Linux User Management Deep Dive course. In this course, students will learn to manage accounts and passwords for Linux users and groups. We’ll review user and group IDs, user shells, working with home directories, and user management files such as /etc/passwd, /etc/group, /etc/shadow, and /etc/gshadow. Then we’ll discuss creating users and groups, modifying their settings, and removing users and groups from the system.Next, we’ll dive into password management and talk about how passwords are encrypted. We’ll also discuss password aging features and demonstrate the differences between password and account locking, inactivity periods, and expiration. Lastly, we’ll dig into user and group security troubleshooting where we’ll introduce sudo, managing file permissions, access control lists, configuring user and group disk quotas, and troubleshooting login issues.
