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

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.
