I do need to run the commands at exactly the same time. It has nothing to do with making my command more "robust". It has "everything" to do with "visual" presentation that someone viewing the 10 boxes will see. if the 10 boxes are not in sync it will be completely obvious and crappy. So if cron/at does not support it - I'll find another way. Thanks everyone! Jerry
