Execute a command asynchronously while redirecting the output to a file in a batch file?

Question

Let\'s say in a batch file, I want to execute myCommand asynchronously (without waiting for it to finish). And I don\'t want to execute myCommand in a new

Answer 1

Nearly like dbenhams answer, but you need to force the redirection to the new thread, not to the start command.

start "myTitle" "myCommand > output.txt"

Answer 2

I haven't tested it fully, but I think this may work:

start /b "" myCommand >output.txt

I believe both forms work fine - the only difference is if standard error is redirected as well and START fails to launch myCommand.

Redirecting START: both myCommand and START output are redirected to the file.

start /b "" myCommand >output.txt >2&1

Redirecting myCommand only: Only myCommand output is redirected. Any START error message will appear on the screen. Note, I opted to escape the redirection instead of using quotes like jeb.

start /b "" myCommand ^>output.txt ^>2^&1
