NAME

halt − stop the processor

SYNOPSIS

/usr/sbin/halt [ −lnqy ]

AVAILABILITY

SUNWcsr

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. 

OPTIONS

−l Suppress sending a message to the system log daemon, syslogd(1M) about who executed halt. 

−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
