reboot, halt - stopping and restarting the system
The halt and reboot utilities flush the file system cache to disk, send
all running processes a SIGTERM (and subsequently a SIGKILL) and,
respectively, halt or restart the system. The action is logged,
including 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.

halted or restarted, giving users advance warning of their impending
utmp(5), boot(8), shutdown(8), sync(8)
A reboot command appeared in Version 6 AT&T UNIX.
