DOS batch file question

Hey guys...
How do you suppress error messages in a DOS file that runs in Win2000/XP?

This is a file to be clicked on by external reps to connect shared folders to their computer...

@ECHO OFF
REM ___Company Share Directory_____
ECHO.
ECHO.
ECHO.
ECHO --Connecting Company Share Directory--
NET USE T: \\SERVER_NAME_REMOVED\CompanyShare
If NOT errorlevel 1 GOTO next
ECHO.
ECHO *** An error occured during Connection to Company Share Directory ***
ECHO Drive not connected

REM ___Sales Directory______
:next
ECHO.
ECHO.
ECHO.
ECHO --Connecting Sales Directory--
NET USE S: \\SERVER_NAME_REMOVED\Sales
If NOT errorlevel 1 GOTO last
ECHO.
ECHO *** An error occured during Connection to Sales Directory ***
ECHO Drive not connected

REM ___Keep Window Open to View Results________
:last
ping -n 5 localhost >nul

Should the connection fail, I'd like it to say the error message I have created, not Error 53, Connection not found, or whatever.
I tried using CTTY NUL and adding >CON to all echo's, but CTTY has been removed.

Any thoughts or suggestions?
 
pipe the output of the net command to NUL

ie
NET USE T: \\SERVER_NAME_REMOVED\CompanyShare > NUL

[edit] actually that will just prevent the output from being displayed, i suppose you could pipe it to a variable and then check its value, which is no trivial task in batch [/edit]
 
sgarissta -> yeah, I tried that. It works for the ping command, but for some reason it doesn't for the NET USE command.

BTW what I'm doing to guarantee a fail is to incorrectly spell the share folder name. ie \\xxx\companyshar
 
Probably because NET uses stderr instead of stdout to write to. > only redirects stdout. AFAIK, you can't redirect stderr with the windows CLI.


nitpick : it's not DOS if you're under NT.
 
XP cmd.exe can redirect stderr just fine. I did it yesterday.
 
STL ->What's your take on how to supress a NET USE error command? Do you have a quick and dirty switch or code to hide it?
 
C:\Temp>net use \\mlar 2> NUL

C:\Temp>net use \\mlar
System error 53 has occurred.

The network path was not found.


C:\Temp>
 
STL -> I've tried every possible combination of spaces and uppercase letters with > NULL, but I still get results exactly as your example.

Did yours actually run, or are you showing an example based on your experience and knowledge?

This is a .bat file that will be clicked on while in the WinXP/2000 environment... does that change anything?

NUL, one L.

> but I still get results exactly as your example.

Isn't my example... what you want?

> Did yours actually run

Yes, I typed it in by hand.

> This is a .bat file that will be clicked on while in the WinXP/2000

Shouldn't matter.
 
STL -> Sorry, typed too fast...yes, I am using NUL, not null...

What I would like to have happen is;

this error message is supressed:
System error 53 has occurred.

The network path was not found.

My coded error message is shown:
*** An error occured during Connection to Company Share Directory ***
Drive not connected

At the moment, both show up, even with the >nul at the end of the NET USE command line.
 
I did, and did not realize that was part of the code, I thought it was part of the name of the share... I do apologize!!!

It does indeed work, THANKS VERY MUCH!!!

Can you get technical and explain what it is doing?
Is it an IF command...If errorlevel 2, output to Nul?
 
> It does indeed work, THANKS VERY MUCH!!!

A wootness in the sky.

> Can you get technical and explain what it is doing?

It's redirecting the standard error stream to NUL. 0 is standard input, 1 is standard output, 2 is standard error.

Also, ameoba owes me one cookie now. Chunky, not that god damn chewy kind, you hear.
 
well since this is a dos batch file based thread I thought I'd ask a question here to keep the threads down. This may well be a very stupid and newb question but I'm not very familiar with batch files in general. I have a batch file that connects to an ftp server uploads a zip file, writes all the info to a log file and then quits (this isn't warez related at all, a client support thing actually). Is there anyway whatsover to run this file without visually opening a dos/cmd window on the user's screen?

Thanks much and forgive me if it's an obviously daft question.
thanks.
 
I have done this before but i cant remember how atm. I know it involves a very short vb script tho, i'll keep looking and see what i can find.
