NAME

reboot − restarting the UNIX operating system

SYNOPSIS

/etc/reboot [ −n ] [ −q ]

DESCRIPTION

reboot runs the reboot(2) system call to restart the UNIX kernel.  The kernel is loaded into memory by the PROM monitor, which transfers control to it.  Since the system cannot be reentered, it is read in from disk or tape each time it is bootstrapped.  See boot(8S) for details.

Although reboot can be run by the super-user at any time, shutdown(8) is normally used first to warn all users logged in of the impending loss of service.   See shutdown(8) for details.

reboot performs a sync(1) operation on the disks, and then a multiuser reboot is initiated. See init(8) for details.

OPTIONS

−n Avoid the sync(1). It can be used if a disk or the processor is on fire.

−q Quick.  Reboots quickly and ungracefully, without first shutting down running processes. 

Power Fail and Crash Recovery

Normally, the system will reboot itself at power-up or after crashes.
