Overview: Do I Need to Set Environment Variables?
Deciding to Set
Environment
Variables Although it is not essential to set environment variables, setting
environment variables can simplify the operation of your system.
You set environment variables from console mode. The ideal
time to set environment variables is before you boot operating
system software. If your operating system is up and running,
you must invoke console mode. (Refer to Invoke Console Mode in
Chapter 1.)
After you have finished setting environment variables, you can
begin or resume operating your system in operating system
mode.
What Variables
Can I Set? Table 4–1 describes the environment variables and their factory
settings.
Displaying
Current
Environment
Variables You can use the
show
command to display the current setting of
any environment variable described in Table 4–1. For instance,
to display the current setting of the auto_action environment
variable, enter the following:
>>> show auto_action
Return
The system responds with a display similar to the following:
auto_action boot
In this example, the auto_action environment variable is set to
boot.
