NAME

reboot − reboot the system

SYNOPSIS

/etc/reboot [  −h  ] [  −n  ] [  −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. 

When UNIX is running reboot can be used to halt the system in an orderly fashion.  reboot causes the disks to be synced, and a reboot to be initiated. 

Options to reboot are:

−h halts the system without rebooting. 

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

−q reboots quickly, without executing commands in /etc/rebootrc.
