37.2. User and Group Management Tools
Managing users and groups can be a tedious task; this is why Red Hat Enterprise Linux provides tools and conventions to make them easier to manage.
The easiest way to manage users and groups is through the graphical application, User Manager (
system-config-users). For more information on User Manager, refer to Section 37.1, “User and Group Configuration”.
The following command line tools can also be used to manage users and groups:
