halt(1Mbsd)

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
