This will suppress echoing all the input commands. For standard output also try “@echo off” at the start of the batch file. This will suppress echoing all the input commands.

I've been redirecting stderr that way in unix for many years, but I've never tried it in dos. I wouldn't have thought to try. I also didn't know there was an eqivalent to /dev/null in dos. Great stuff! Quinn Greg,

It will redirect STDOUT to null. Errors will still be displayed. As an example, run <strong>dir badfile.txt >nul </strong>and you will still see "File not found" displayed. That's because errors are written to STDERR To redirect STDERR to nul as well, try this: <strong>dir badfile.txt > nul 2&>1</strong> Of course you may want to see the errors. So a better tack to take could be to write to a log file <strong>dir badfile.txt >log.txt 2&>1</strong> \Greg This tip is good but it only goes so far. It will redirect STDOUT to null.
