I was investigating an admin devtest failure and was trying to clean up after aborting the test run.
The delete-local-instance command works, but delete-instance complains as below:
tjquinn-mac:cli tjquinn$ asadmin list-instances
12249-ins0 not running
12249-ins1 not running
12249-ins2 not running
Command list-instances executed successfully.
tjquinn-mac:cli tjquinn$ asadmin delete-instance 12249-ins0
Option terse is required but was not specified
