HALT(8) 						      System Manager's Manual							   HALT(8)

halt - abruptly stop the system SYNOPSIS
Halt stops the system almost immediately. The users are not informed about the things to come. Halt is logged in /usr/adm/wtmp and in /usr/adm/authlog, if these files exist. Halt should only be run by the super-user, any other caller will be refused. Halt is a rather rude program. Shutdown(8) is preferred for it performs a more gentle halt routine. Halt -f is even worse, it omits the terminate signals that are normally sent first to all processes to give them a chance to die peace- fully. SEE ALSO
reboot(2), shutdown(8), reboot(8), boot(8). AUTHOR
