4.2 Un i x Conguration
One of the strengths of the Un i x operating system is its flexibility. The system
administrator configures the workstation to the needs of the local user
community, and the users can fine-tune their own environments.
The following subsections contain instructions for performing common system
administration tasks on an IRIS workstation. To perform these tasks, become
the super-user by logging in as root:
IRIS login: root
Once you are logged in as root, you can return to a login shell by entering the
exit command.
For more information on Un i x configuration, see the Un i x Programmer’s Manual
and the list of configuration files in Section 4.2.4.
