Turn off Screen Output

Is there a way to turn off standard output while processing is going on? I have tried redirecting to /dev/null but that is not working because some of the commands invoke a profile. I would like to temporarily turn off the screen output until the processing is complete. Sort of like a splash screen while everything is being intialized.

Thanks.
