I have been unable to redirect output to a file in DOSBox (version 0.74), via:
dosomething.bat >testout.txt 2>&1
where the ">" sign in a regular DOS window redirects the output (stdout) of a command to a file, and the "2>&1" redirects stderr to the same place as stdout.

The Dosbox console window says "SHELL:Redirect output to testout.txt", but the output still goes to the main Dosbox window. File "testout.txt" is created, but its empty. I varied the Dosbox cycle speed, with no effect. I want to save the output from compiling, but it is scrolling off the window.

Thanks very much.

try without the 2>&1 part
although the compiler might be using something else than stdout to display stuff (directly int 29 for example)

I have previously observed that stdout.txt and stderr.txt don't seem to work quite right with the standard 0.74 Windows build of DOSBox.
Re: The "-printconf" switch

As is so often the case, you may have better luck with the SVN Daum version.

I had already tried both with and without the "2>&1". May be a bug in 074 version. I'm familiar with this compiler, it sends to stdout/stderr.

I'm not familiar with the SVN Daum version of Doxbox, I have to go thru my IT dept and they take almost FOREVER to approve stuff.

Thanks for the replies.

To be clear: are you running DOSBox.exe with the -noconsole switch?

It doesn't make any difference if I use the -noconsole switch or not, the output doesn't get redirected to a file. Without the -noconsole switch, the console window gives the message "SHELL:Redirect output to testout.txt", but that doesn't happen.
