Reading the manpage for shutdown and for halt: HALT sends all running processes a SIGTERM and then a SIGKILL if needed SHUTDOWN runs through the INIT shutdown scripts What does this mean? If ALL your processes can be shutdown via a SIGTERM then you're fine, but if you have processes like a MySQL db or something which needs a special shutdown command passed to it in order to exit cleanly or process something, this will not be executed and data corruption or something else nasty "could" occur. Hope that helped. Henrik On Sunday 10 March 2002 16:28, Chip Wiegand wrote: > I read that there is a differance between using - > halt and shutdown.
