Canceling a Command

You can attempt to cancel a command as long as the service shows that it is in either a Pending or Executing state. However, even if a command is still in one of these states, we cannot guarantee that the command will be terminated and the underlying process stopped.

To cancel a command using the console

  1. In the navigation pane, choose Run Command.

  2. Select the command invocation that you want to cancel.

  3. Choose Actions, Cancel Command.

To cancel a command using the AWS CLI

Use the following command.

aws ssm cancel-command --command-id "command ID" --instance-ids "instance ID"

For information about the status of a cancelled command, see Setting Up Events and Notifications.
