I have a command I am running produces a ton of output, I want to silence the output without writing to a file. I have used the following to send all output to a file, but again I don't want any file output:

command > out.txt 2>&1

I have used command > /dev/null on my CentOS box before, but I can't find a similar thing for windows.

I hope you used command > /dev/null on your CentOS. –  Kurt Pfeifle Aug 2 '10 at 20:43

If you indeed used command > /bin/null on CentOS, you have created a common file file named /bin/null on your system. You may say 'It worked!', if you want. This file now contains the stdout and stderr output of your command. Usually, in /bin/ there are only executable files. And usually, only the root user is allowed to create files there. So if that file is there, you did run your command as root user... /bin/null usually doesn't exist -- and /dev/null (which I mentioned) usually is used as the 'black whole' where unwanted output should disappear in... –  Kurt Pfeifle Aug 11 '10 at 23:13
    
Good point, I hadn't thought of that. However, I am pretty sure it is just my faulty memory because I was on Windows at the time. –  Alec Gorge Aug 18 '10 at 3:15

You want command > nul 2>&1.

This only redirects stdout. You also need > nul 2>&1 or 2> nul to kill stderr. –  grawity Apr 16 '10 at 14:02
    
Yes I know that, but thanks for mentioning it for others that visit this question! –  Alec Gorge Apr 19 '10 at 20:52
