NNAAMMEE
       halt, reboot - stop the system.

SSYYNNOOPPSSIISS
       //bbiinn//hhaalltt [--tt _s_e_c] [--nnqq]
       //bbiinn//rreebboooott [--tt _s_e_c] [--nnqq]

       HHaalltt  and  rreebboooott  send	all processes the warning signal,
       then wait for 10 seconds, then send all processes the kill
       signal.	After	that  the  system  is  either  halted  or
       rebooted.

OOPPTTIIOONNSS
       --nn     Don't sync before reboot or halt.

       --qq     Do a `quick' reboot or halt, don't send the warning
	      signal.

       --tt _s_e_c Wait  _s_e_c	seconds  between  sending  processes the
	      warning and the kill signal.

DDIIAAGGNNOOSSTTIICCSS
       If you're not the superuser,  you  will	get  the  message
       `Can't idle init'.

NNOOTTEESS
       _R_e_b_o_o_t  and _h_a_l_t shouldn't be called directly, but only by
       a frontend like _s_h_u_t_d_o_w_n(1).  Even better, they should  be
       builtin	to  _s_h_u_t_d_o_w_n.	However, historical practice pre-
       vents this.

       _H_a_l_t and _r_e_b_o_o_t are just links to the same program, so the
       man  page  should  be  installed	twice,	as hhaalltt..88 and as
       rreebboooott..88.
