While you can't execute programs that begin with '/', you CAN change your PATH variable. This sort of removes a lot of the restrictions. Does anyone know about all the things sh will restrict? As far as I have ever been able to determine it is a totaly undocumented feature of the shell (at least on 4.x). Joe
