NAME
reboot, halt, poweroff - reboot or stop the systemSYNOPSIS
reboot [OPTION]...halt [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.
