halt(1Mbsd) (BSD System Compatibility)


halt -- (BSD) stop the processor

Synopsis

   /usr/ucb/halt [-lnqy] 

Description

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

halt -l 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.

Command options

-l
Logs a message to the system log indicating who halted the system.

-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
