4.2 U

Configuration
One of the strengths of the U
nix
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 U
nix
configuration, see the U
nix
Programmer’s Manual
and the list of configuration files in Section 4.2.4.
