如何将输出重定向到批处理文件中的文件？

Question

In Windows 7, I have a batch file that runs an exe in the sub-directory of bat file, it first changes current directory to that folder, then runs the exe. But something goes wrong, I see a console window for a very short time and the program doesn't start. Since the output console is displayed for less than a second, I can't see the error message.

bat file is:

cd /d "%~dp0my_subfolder"
start "" myapplication.exe

How do I redirect the output error message to a text file (the text file will be in the same directory with bat file), so that I can read the error message? What command should I add to the bat file above?

Answer 1

use:

 start "" myapplication.exe > mytextfile.txt 2>&1

instead you could run batch file from cmd to know what is the error

Answer 2

Try this, to see the error message:

cd /d "%~dp0my_subfolder"
start "" /b myapplication.exe
pause
