NAME
reboot, halt, poweroff - reboot or stop the system
SYNOPSIS
reboot [OPTION]...
halt [OPTION]...
poweroff [OPTION]...
DESCRIPTION
These programs allow a system administrator to reboot, halt or poweroff
the system.
When called with --force or when in runlevel 0 or 6, this tool invokes
the reboot(2) system call itself and directly reboots the system.
Otherwise this simply invokes the shutdown(8) tool with the appropriate
arguments.
Before invoking reboot(2), a shutdown time record is first written to
/var/log/wtmp
OPTIONS
-f, --force
Does not invoke shutdown(8) and instead performs the actual
action you would expect from the name.
-p, --poweroff
Instructs the halt command to instead behave as poweroff.
-w, --wtmp-only
Does not call shutdown(8) or the reboot(2) system call and
instead only writes the shutdown record to /var/log/wtmp
--verbose
Outputs slightly more verbose messages when rebooting, useful
for debugging problems with shutdown.
ENVIRONMENT
RUNLEVEL
reboot will read the current runlevel from this environment
variable if set in preference to reading from /var/run/utmp
FILES
/var/run/utmp
Where the current runlevel will be read from; this file will
also be updated with the runlevel record being replaced by a
shutdown time record.
/var/log/wtmp
A new runlevel record for the shutdown time will be appended to
this file.
