Hello,

I run a bunch of batch commands at the end of my Unattended DVD. Via '@echo off' I was able to hide the command prompt, however lots of commands still send s "Operation completed successfully". Is there a way to suppress those messages?

Reg.exe is one example, and it doesn't feature a switch to turn these messages off, so is there a global option to turn those messages off?

Thanks for your help,

They are all adding information to the registry via the REG ADD command aren't they?

If you were to use the syntax I again gave you here then you wouldn't need to ask this question!

Clue: last four characters

Sorry, I never saw your last reply in that other topic because my problem was solved meaning I didn't visit that topic anymore.

Does the /f>Nul also work for copy commands? Whenever I copy a file, it shows me "Copied 1 file(s) successfully" or something like that. I'd liek to get rid of that too. "copy /?" didn't show anything useful, I only found a switch in there to skip the confirmation upon overwriting files.

Yes, the following:

Copy [source] [destination] >Nul

will suppress the echoing of 'copied n file(s) successfully'

Yes, the following:

Copy [source] [destination] >Nul

will suppress the echoing of 'copied n file(s) successfully'

OK so, is there much this doesn't work for?

Up to now it works for...

DEL

REG

Even though those command line programs do not show any support for >Nul

I guess its trial and error the same as always.

Basically, in the windows command line, the > character sends the output of whatever you're running to whatever is to the right of the > character. So, if you were to do

echo test > text.txt

Then test.txt would say "test" inside. Nul happens to be special in that Nul is Nul - that is, it's not there. It's sort of like sending it to nowhere. So by sending the output to nowhere, there is no output.

Be warned that using > repalces the existing file if there is already one, so in the above example, if test.txt had content already, it would've been erased. >> appends the output to an existing file or creates a new one if none exists, and may be more suitable for some situations.

Read here about REDIRECTION:

http://www.robvanderwoude.com/redirection.html

Redirection is not documented inside ANY command as it is a "generic" feature of the OS.

Since some commands output to "standard error" instead of "standard output" in some case you will need to use the:

command > NUL 2>&1

syntax
