As mentioned, some things won't work by default. For most things, if you just want to silence output (usually in a .BAT file), try this: REM ... shut up almost all output ... ctty nul echo (do whatever) ctty con REM ... make sure to re-enable "ctty con" at the end!! ... To redirect STDERR to file, you need a third-party util (or a better shell like 4DOS, as already mentioned): * http://cd.textfiles.com/simtel/simtel0101/simtel/asmutl/stderrf1.zip There's also DJGPP's REDIR.EXE (386 DPMI) from DJDEV205.ZIP : * http://www.delorie.com/pub/djgpp/current/v2/djdev205.zip _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
