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.
