NAME

unset - removes one or more variables from the multimode environment

SYNOPSIS

unset env_var [env_var] *

DESCRIPTION

Removes one or more variables you set for the multimode environment. The variables and their associated values will no longer exist in the environment.

OPERANDS

env_var: environment variable to be removed.

EXAMPLES

Example 1. Using unset to remove environment variables

asadmin> export AS_ADMIN_HOST=bluestar AS_ADMIN_PORT=8000 AS_ADMIN_USER=admin AS_ADMIN_PASSWORD=password
asadmin> export AS_ADMIN_PREFIX=server1.jms-service
asadmin> export
AS_ADMIN_HOST=bluestar
AS_ADMIN_PORT=8000
AS_ADMIN_USER=admin
AS_ADMIN_PASSWORD=********
AS_ADMIN_PREFIX=server1.jms-service
asadmin> unset AS_ADMIN_PREFIX
asadmin> export
AS_ADMIN_HOST=bluestar
AS_ADMIN_PORT=8000
AS_ADMIN_USER=admin
AS_ADMIN_PASSWORD=********

Using the export command without the argument lists the environment variables that are set. Notice the AS_ADMIN_PREFIX is not in the environment after running the unset command.
