- Welcome to lesson nine.
In this lesson, you'll learn how to manage users and groups.
I'll explain why users are necessary in Linux environments
and our users are required for setting permissions.
Next you'll learn how to add users
and groups using useradd and groupadd.
Once you know about that, I'll explain all
about different properties of users, groups, and passwords
and you'll learn how to configure defaults for new users.
I'll then show you how to use the login CTL session manager.
And at the end of this lesson,
you'll find a list of the commands that were covered,
as well as the end of lesson lab and solution.
