Redirect output from "start"-ed console

[element]

I have a test.bat which contains just this: "echo blah". When I run

test.bat > output.txt

I get output.txt containting "blah". How do I redirect the output if test.bat is launched with "start":

start "test" test.bat > output.txt

I get no output.txt. I tried escaping the ">" with "^" and "\", but no dice.

Maybe

start "%_cmdspec" /c test.bat ^> output.txt

 

[element]

start "%_cmdspec" /c test.bat ^> output.txt

Still nothing. BTW, I believe the first param for "start" would be the console title:

start "test" "%_cmdspec" /c test.bat ^> output.txt

This works:
start "title" /pgm "%_cmdspec" /c test > output.txt

Note the use of /pgm to force the quoted argument to be considered as the program to be executed; /c to make the session terminate upon command completion. The START command considers the first string following /PGM to be the file specification of the program to be executed, and everything thereafter as parameters to be passed to the program to be executed.

This works: start "title" /pgm "%_cmdspec" /c test > output.txt

Yes, it does, thanks. It even works from a batch file, without escape characters.

It works for me, although I'm not sure why:
