SYNOPSIS

DESCRIPTION

13       shutdown  provides an automated procedure to notify users when the sys‐
14       tem is to be shut down. time specifies when  shutdown  will  bring  the
15       system down; it may be the word now (indicating an immediate shutdown),
16       or it may specify a future time in one  of  two  formats:  +number  and
17       hour:min.  The first form brings the system down in number minutes, and
18       the second brings the system down at  the  time  of  day  indicated  in
19       24-hour notation.

22       At intervals that get closer as the apocalypse approaches, warning mes‐
23       sages are displayed at terminals of all logged-in users, and  of  users
24       who have remote mounts on that machine.
25
26
27       At  shutdown  time  a message is written to the system log daemon, sys‐
28       logd(1M), containing the time of shutdown, the instigator of the  shut‐
29       down,  and  the  reason. Then a terminate signal is sent to init, which
30       brings the system down to single-user mode.

OPTIONS

33       As an alternative to the above procedure, these options can  be  speci‐
34       fied:
35
36       -f    Arrange,  in  the manner of fastboot(1B), that when the system is
37             rebooted, the file systems will not be checked.
38
39
40       -h    Execute halt(1M).
41
42
43       -k    Simulate shutdown of the system. Do not actually  shut  down  the
44             system.
45
46
47       -n    Prevent the normal sync(2) before stopping.
48
