NAME

reboot − UNIX bootstrapping procedures

SYNOPSIS

/etc/reboot [ −n ] [ −q ] [ −Q ]

DESCRIPTION

UNIX is started by placing it in memory at a particular location and transferring to that location.  Since the system is not reentrant, it is necessary to read it in from disk or tape each time it is to be bootstrapped. 

Rebooting a running system.  When UNIX is running and a reboot is desired, /etc/reboot can be used.  Reboot causes the disks to be synced, and a reboot (as described below) to be initiated. 

Options to reboot are:

−n avoids the sync.  It can be used if a disk or the processor is on fire. 

−q reboots quickly, without gracefully shutting down running processes first.  This is the default. 

−Q inhibits −q.  The −Q flag causes /etc/rebootrc to be invoked which causes all processes to be sent a terminate signal, followed by a kill signal a few seconds later.  The kill signal kills all processes that did not voluntarily exit upon receipt of the terminate signal.
