How do I capture all the output from a CLI program?

Question

I need to capture all the messages from cmd.exe.

I tried abc.exe &> res.dat, but it doesn't seem to work with stderr or others. What should I do?

Reconstruct your command like so:

abc.exe >res.dat 2>&1

This will send STDERR to the same location.

	OP wants to capture all output from `cmd.exe` not `abc.exe` -- I think the difference matters. – martineau Feb 24 '11 at 20:54
	What other messages will cmd output when he is running `abc.exe`? ... – John T Feb 25 '11 at 1:46
	Oh, I don't know, maybe `'abc.exe' is not recognized as an internal or external command, operable program or batch file.` – martineau Jul 20 '11 at 14:48
	@martineau, that string is part of standard error and will be captured by my command, but thanks for playing. – John T Jul 20 '11 at 18:24
