at 6:50PM "c:\winnt\task.bat"
Performing this command would run the task.bat file at 6:50PM today unless the task is scheduled after the time specified. Because the /interactive switch is not in the command, this batch file will be executed in the background.

Runs the beep.bat batch file at 6:50PM with the ability for the user to interact with the batch file.
at 1 /delete
