NAME

       rc - command script for auto-reboot and daemons

SYNOPSIS

       /etc/rc
       /etc/rc.local

DESCRIPTION

       Rc is the command script which controls the automatic reboot and rc.local is the script holding commands which are pertinent only to a spe-
       cific site.

       When an automatic reboot is in progress, rc is invoked with the argument autoboot and runs a fsck with option -p to ``preen'' all the disks
       of  minor  inconsistencies  resulting from the last system shutdown and to check for serious inconsistencies caused by hardware or software
       failure.  If this auto-check and repair succeeds, then the second part of rc is run.

       The second part of rc, which is run after a auto-reboot succeeds and also if rc is  invoked  when  a  single  user  shell  terminates  (see
       init(8)), starts all the daemons on the system, preserves editor files and clears the scratch directory /tmp.  Rc.local is executed immedi-
       ately before any other commands after a successful fsck.  Normally, the first commands placed in the rc.local  file  define  the  machine's
       name,  using  hostname(1), and save any possible core image that might have been generated as a result of a system crash, savecore(8).  The
       latter command is included in the rc.local file because the directory in which core dumps are saved is usually site specific.

NAME

       reboot - Restarts the machine

SYNOPSIS

       /usr/sbin/reboot [-dlnq]

DESCRIPTION

       When  the  system  is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation.  If no users are
       logged in, use the reboot command.

       The reboot command normally stops all running processes, syncs the disks, logs the reboot,  and	writes	a  shutdown  entry  in	the  login
       accounting file, /var/adm/wtmp.

       The  reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard-
       ware time-of-day clock.	After these activities, the system reboots.  By default, the system starts and the file systems are  automatically
       checked.  If the start-up activities are successful, the system comes up in the default run-level.

       You must have root privileges to use this command.  Using the -n flag can result in file system damage.

FLAGS

       Generates  a  crash  dump  of the system before halting it.  Can be used with any of the other flags.  Does not log the reboot using syslog
       Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not  log
       the reboot using syslog

EXAMPLES

       To  enable  the	default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the
       shutdown, and perform other routine shutdown and reboot activities.  To shut down the system without logging the reboot, enter:	reboot	-l
       This  command  shuts  down  the	system and performs all shutdown and reboot activities, except logging the shutdown.  To reboot the system
       abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes.
