RC(8)                       System Manager's Manual                      RC(8)

       rc - command script for auto-reboot and daemons


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

       When  an  automatic reboot is in progress, rc is invoked with the argu-
       ment 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  fail-
       ure.   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.

       init(8), reboot(8), savecore(8)
