The machine does not reboot, even if the auto-reboot switch 12 is set on the console. 13 14 Available options for hhaalltt: 15 16 --nn No sync before stopping. 17 18 --qq Quick halt, no graceful shutdown is attempted. 19 20 --yy This option is needed if you are trying to halt the system from a 21 dialup. 22 23 HHaalltt normally logs the shutdown using syslog(8) and places a shutdown 24 record in the login accounting file /_v_a_r/_l_o_g/_w_t_m_p. These actions are 25 inhibited if the --nn or --qq options are present. 26 27SSEEEE AALLSSOO 28 reboot(8), shutdown(8), syslogd(8) 29 30BBUUGGSS 31 It is very difficult to halt a VAX, as the machine wants to then reboot 32 itself. A rather tight loop suffices. 33 34HHIISSTTOORRYY 35 The hhaalltt command appeared in 4.0BSD. 36 374th Berkeley Distribution March 16, 1991 1 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67
