NAME

halt − stop the processor

SYNOPSIS

/usr/ucb/halt [ −nqy ]

DESCRIPTION

halt writes out any information pending to the disks and then stops the processor. 

halt normally logs the system shutdown to the system log daemon, syslogd(1M), and places a shutdown record in the login accounting file /var/adm/wtmp.  These actions are inhibited if the −n or −q options are present. 

The following options are available:

−n Prevent the sync before stopping. 

−q Quick halt.  No graceful shutdown is attempted. 

−y Halt the system, even from a dialup terminal. 

FILES

/var/adm/wtmp login accounting file

SEE ALSO

reboot(1M), syslogd(1M), shutdown(1M), init(1M). 

NOTES

This command is equivalent to init 0.
