Using Environment Variables; Set Envar - Compaq DS10L - AlphaServer - 256 MB RAM Reference Manual

2.13 Using Environment Variables

Environment variables pass configuration information between
the console and the operating system. Their settings determine
how the system powers up, boots the operating system, and
operates. You issue an init command to activate a new
environment variable.
Environment variables are set or changed with the set envar command (where
envar is a placeholder for the environment to be changed) and set to default
values with the set -default envar command. Their values are viewed with the
show envar command. User-defined nonvolatile environment variables are
created with the edit command described in Section 2.4. Section 2-18 describes
the predefined SRM console environment variables in detail.
2.13.1

set envar

The set command sets or modifies the value of an environment
variable. It can also be used to create a new environment
variable if the name used is unique. Environment variables are
used to pass configuration information between the console and
the operating system. The setting of these variables determines
how the system powers up, boots the operating system, and
operates.
Syntax: set [-default] envar value
-default Restores an environment variable to its default setting.
envar The name of the environment variable to be displayed. The
wildcard * displays all environment variables, which are:
console, kbd_hardware_type, language, ocp_text
and os_type
value The new value of the environment variable.
Whenever you modify the value of any environment variables, the new value
takes effect only after you reset the system by pressing the Halt/Reset button or
issuing the initialize command.
