How to redirect output from exe after it has terminated?

Question

I'm trying to save the output of an exe file executed within a batch file to a text file. I've tried the the following methods but they don't work

This doesn't work since I'm back at the command prompt while the application runs and the text file created is blank.

C:\>myexec.exe > mytext.txt

C:\>_

C:\>Status: Passed

These also doesn't work. I get an empty text file and no output.

C:\>start /wait myexec.exe > mytext.txt

C:\>call start /wait myexec.exe > mytext.txt

This gives me an output at least:

C:\>start /wait myexec.exe
Status Passed

Answer 1

The & redirection operator duplicates output or input from one specified handle to another specified handle. For example, to send dir output to File.txt and send the error output to File.txt, type:

dir>c:\file.txt 2>&1

Answer 2

Use /B operator.

This will cause the output to be redirected

start /B /wait myexec.exe > mytext.txt

Answer 3

I had the same issue and solved it like this:

bat file content

START /wait cmd /c "F:\MyInstaller\installer.exe > log.txt"

echo This will get logged after the previous is completed > log1.txt

Answer 4

Try Application.exe >& file.txt. This will output both, standard output and error stream, to your file.
