Name

reboot − automatic reboot procedures

Syntax

/etc/reboot [ −n ] [ −q ]

Description

The ULTRIX system is booted by loading a kernel image, usually /vmunix, into memory at location zero and transferring to zero. Because the system is not reenterable, the kernel image must be read in from disk each time the system is bootstrapped.

When the reboot of a running system is desired, shutdown is normally used.  If there are no users, /etc/reboot can be used.  The reboot command causes the disks to be synced, and then a multiuser reboot is initiated.  The system is booted and an automatic disk check is performed. If the procedure succeeds, the system is then brought up for the users.

The system will reboot itself after a power failure or after a crash, provided auto-restart is enabled on your system.  A consistency check of the file systems will be performed and, unless the check fails, the system will resume multiuser operations. 

Options

−nPrevents the disks from being synced. 

−qReboots quickly and ungracefully, without shutting down running processes first. 

Files
