6. User Management Tools
Lesson Content
Most enterprise environments are using management systems to manage users, accounts and passwords. However, on a single machine computer there are useful commands to run to manage users.
Adding Users
You can use the adduser or the useradd command. The adduser command contains more helpful features such as making a home directory and more. There are configuration files for adding new users that can be customized depending on what you want to allocate to a default user.
$ sudo useradd bob You’ll see that the above command creates an entry in /etc/passwd for bob, sets up default groups and adds an entry to the /etc/shadow file.
Removing Users
To remove a user, you can use the userdel command.
$ sudo userdel bob This basically does its best to undo the file changes by useradd.
Changing Passwords
$ passwd bob This will allow you to change the password of yourself or another user (if you are root).
Exercise
Create a new user then change their password and login as the new user.
