REBOOT(1M) — HP-UX
Series 200, 300, 800 Only
NAME
reboot − reboot the system
SYNOPSIS
/etc/reboot [ −h | −r ] [ −n | −s ] [ −d device ] [ −f lif_filename ] [ −t time ] [ −m message ]
DESCRIPTION
Reboot terminates all currently executing processes, except those essential to the system, then halts or reboots the system. Reboot with no arguments syncs all disks before rebooting the system. The options are:
−h shutdown the system and halt.
−r shutdown the system and reboot automatically. (default)
−n do not sync the file systems before shutdown.
−s sync the file systems before shutdown; for file systems which were cleanly mounted, modify the fs_clean flag from FS_OK to FS_CLEAN. (default)
−d device reboot from the specified device. The device must be a lif volume. This option cannot be used with -h.
−f lif_filename
reboot from the specified file. If the filename is the NULL string, the power up search sequence will be made for a system. Otherwise, the filename has to follow the lif filename convention. This option cannot be used with -h.
−t time the time when reboot will bring the system down. Time may be the word now (indicating immediate shutdown) or specify a future time in one of two formats: +number and hour:min. The first form brings the system down in number minutes and the second brings the system down at the time of day indicated (as a 24-hour clock).
−m message At intervals that get closer together as reboot time approaches, message is displayed at the terminals of all users on the system.
At shutdown time a message is written in the file /usr/adm/shutdownlog(ifitexists), containing the time of shutdown, who ran reboot, and the reason.
Reboot can be executed only by the super-user.
