halt(1M) System Administration Commands halt(1M) NAME halt, poweroff - stop the processor SYNOPSIS /usr/sbin/halt [-dlnqy] /usr/sbin/poweroff [-dlnqy] DESCRIPTION The halt and poweroff utilities write any pending information to the disks and then stop the processor. The poweroff utility will have the machine remove power, if possible. The halt and poweroff utilities normally log the system shutdown to the system log daemon, syslogd(1M), and place a shutdown record in the lo- gin accounting file /var/adm/wtmpx. These actions are inhibited if the -n or -q options are present. OPTIONS The following options are supported: -d Force a system crash dump before rebooting. See dumpadm(1M) for information on configuring system crash dumps. -l Suppress sending a message to the system log daemon, sys- logd(1M), about who executed halt. -n Prevent the sync(1M) before stopping. -q Quick halt. No graceful shutdown is attempted. -y Halt the system, even from a dialup terminal. FILES /var/adm/wtmpx History of user access and administration information. ATTRIBUTES See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO dumpadm(1M), init(1M), reboot(1M), shutdown(1M), sync(1M), syslogd(1M), attributes(5) NOTES The halt utility does not execute the scripts in /etc/rc_num_.d or exe- cute shutdown actions in inittab(4). To ensure a complete shutdown of system services, use shutdown(1M) or init(1M) to reboot a Solaris sys- tem. The poweroff utility is equivalent to init 5. SunOS 5.9 09 Aug 2000 halt(1M)
