>NUL In a batch file does not hide every output

[Paul]

Hi,

At my work we use an NT4 domain with login scripts for every user.
They look somthing like:

net use g: \\server\share1
net use h: \\server\share2

We wanted to hide the output...
For example "The command completed successfully"

So we added:

net use g: \\server\share1 >nul
net use h: \\server\share2 >nul

This works fine as far as the "The command completed successfully"
message goes. The problem is once the user has logged in once they get
a message saying:

"System error 85 has occurred.

The local device name is already in use."

I want to use the net use ... >nul command but I want NO OUTPUT AT
ALL. Even if the drive failes to map for some reason. I know all about
the net use /p:no option but I want something like >nul but that does
not display anything to the screen. Hope you know what I mean.

Thanks for your time

Paul

Have you tried redirecting both STDERR (channel 2) and STDIN
(channel 1) to NUL? Typical syntax for example DIR command:

DIR ::nofile >NUL 2>&1

There is a "standard out" and also a "standrard error", both of them need to
be redirected to NUL. stdout is 1, or the default if you don't specify a
number. So "net use g: \\server\share1 >nul" is really the same thing as
"net use g: \\server\share1 1>nul".

What you want to hide is stderr, or #2, so try this:

net use g: \\server\share1 >nul 2>nul

Or to get the same effect you can redirect 2 to the same place as 1, which
would look like this:

net use g: \\server\share1 >nul 2>&1

Of course all these hide any real error messages, like 53 if the server is
not available or 5 for access is denied.

The simple solution would be to direct the STDERR to a file.

Thanks all,

Just what I needed.
