Haltsys syncs the disks and shuts down the system (note, though, that it may not actually complete the sync: a sync returns immediately... it does not wait for all the writes to complete). Shutdown kills all interactive sessions other than the console, disable all logins, unmounts each file system individually, makes sure that everything is tidy, and then executes haltsys. It's sort of like checking all the doors and windows before you go out. -- Peter da Silva. `-_-' peter@ferranti.com +1 713 274 5180. 'U` "Have you hugged your wolf today?"
