Perhaps I'm misunderstanding you, but cmd.exe is quite capable of what
you're describing.  (In fact, DOS's command.com is too.)  To redirect
standard output use '> outfile' or '1> outfile'.  To redirect stderr
output, use '2> outfile.err'.  This sends all output to file handle 1
(the same value predefined for stdout) to the file 'outfile', and all
output to file handle 2 (the value predefined for stderr) to file
'outfile.err'.
 
Hmm.  I don't like my explanation much, but it'll have to do for the moment.
