REBOOT(8)                    System Administration                   REBOOT(8)

NAME

       reboot, halt - stopping and restarting the system

SYNOPSIS

       halt -nq
       reboot -nq
       fasthalt -nq
       fastboot -nq

DESCRIPTION

       The halt and reboot utilities flush the file system cache to disk, send
       all running processes a SIGTERM (and subsequently a SIGKILL)  and,  re‐
       spectively,  halt or restart the system.  The action is logged, includ‐
       ing entering a shutdown record into the login accounting file.

       The options are as follows:

              n      If the n option is specified, the file  system  cache  is
                     not flushed.  This option should probably not be used.

              q      If  the  q  option  is specified, the system is halted or
                     restarted quickly and ungracefully, and only the flushing
                     of  the  file  system  cache  is  performed.  This option
                     should probably not be used.

       The fasthalt and fastboot utilities are nothing more than  aliases  for
       the halt and reboot utilities.

       Normally,  the  shutdown(8) utility is used when the system needs to be
       halted or restarted, giving users advance warning  of  their  impending
       doom.
