| /bin/sh uses /dev/tty for job control which is enabled automatically | when running as interactive shell. But there is a -m option where | you can enable/disable it, i.e. 'sh +m' runs a shell with job control | disabled and descriptor 12 not open. And that's correct, rather than what I thought when I replied to the original message earlier. | Maybe kre@ knows if a shell should allow redirection to its | own internal file descriptors. It shouldn't. Fixing that one is trivial. Fixing the fd 13 one is trickier (but will happen). | (Our) ksh only supports the single digit descriptors 0..9 for redirection All ksh versions, I believe. kre
