batch mass-verify

I'd like to mass-verify my MPC library, so I tried a batch like this:

FOR /r %a IN (*.mpc) DO mpcdec -c "%a" >> C:\log.txt
I had in mind to then search for "error occured" in the resulting log file; however, it doesn't work because the output is still written on screen, not in log

Doesn't anybody have an idea? thank you

edit: I really can't find out a solution; since mpcdec is said to write to stdout, the output should be redirected to the log file...

Hmmm, there is something strange, it seems that mpcdec writes to stderr instead of stdout? I've succeeded to redirect the output to a file using

>mpcdec.exe test.mpc >> test.log 2>&1
Of course, this is possible because I have installed UnixUtils in my %PATH%.
I'm affraid with pure windows command prompt this would be impossible.

thank you Antonski, redirecting both stdout and stderr this way works (no need of GNU tool at all)

future versions of mpcdec might want to correct this behaviour ;)

future versions of windows might want to justify more their POSIX compatibility by documenting the streams and their redirection. mpcdec correctly sends output to stdout and diagnostics to stderr.
