Linux servers often contain thousands of users and user files. It’s easier to maintain users if they are contained in groups, but only if the limitations of groups are understood and managed properly. In this course, instructor Grant McWilliams shows you how to manage Linux users and groups using command-line tools.
Learn about Linux user authentication and account policies. Find out how to create, modify, and delete both user and group accounts, as well as assign users to groups, lock accounts and passwords, and force password resets. Explore elevating privileges using group passwords, changing to the super user, and honing your management skills with sudo as you get ready for your next steps as a Linux system administrator.
