ec2-delete-group

Description

Deletes a security group. This action applies to both EC2 security groups and VPC security groups. For information about VPC security groups and how they differ from EC2 security groups, go to Security Groups in the Amazon Virtual Private Cloud User Guide.

[Note]Note

If you attempt to delete a security group that contains instances, or attempt to delete a security group that is referenced by another security group, an error is returned. For example, if security group B has a rule that allows access from security group A, security group A cannot be deleted until the rule is removed.

The fault returned is InvalidGroup.InUse for EC2 security groups, or DependencyViolation for VPC security groups.

The short version of this command is ec2delgrp.
