The following sections survey the contents of the chapters in this manual.
In general, the first few chapters contain information about the setup tasks
you perform the first few hours after installing or updating new operating
system software.
The several remaining chapters contain information about the schedule-
and event-driven tasks that make up the bulk of a system administrator’s
work. These tasks use the operating system components, its services, or
features to maintain the performance of the operating system and the
satisfaction of its users.
1.2 Starting Up and Shutting Down the System
Chapter 3 contains instructions for booting and for shutting down systems.
You will need this information for the following tasks:
• System testing or troubleshooting
When you test or troubleshoot your system, you need to move between
run levels, for example, from multiuser mode to single-user mode.
• Setting the system clock
If your system has been powered down for an extended amount of time,
you will need to set the system clock.
1.3 Customizing the System Environment
Periodically, you will need to tailor your system to fit your needs. For
example, you might need to:
• Modify system files to add information about new devices or to invoke
certain programs when the system moves from one run level to another.
• Specify commands to be run automatically at a specific time.
