That way they can still hit your inode quota, plus you can't keep hard links yourself: Any rm(1) would clobber the file for good. But in any case, if your environment is *this* hostile, you better take really extraordinary measures. And there I'm afraid the rather weak traditional Unix security model is way out of question anyway. I'd start thinking of relocating, myself. -- Horst von Brand vonbrand@sleipnir.valparaiso.cl Casilla 9G, Viña del Mar, Chile +56 32 672616
