Suppress command line output

Question

I have a simple batch file like this:

echo off

taskkill /im \"test.exe\" /f > nul

pause

If \"test.exe\" is not running, I get this message:

Answer 1

mysqldump doesn't work with: >nul 2>&1
Instead use: 2> nul
This suppress the stderr message: "Warning: Using a password on the command line interface can be insecure"
