SYNOPSIS

reboot [OPTIONS...]

DESCRIPTION

reboot restarts the machine. It communicates with the system manager (systemd) to perform the reboot. The command accepts the same options as the related poweroff and halt commands.

PARAMETERS

--halt

Halt the machine instead of rebooting

-p, --poweroff

Power off the machine instead of rebooting

--reboot

Reboot the machine (default action)

-f, --force

Force immediate reboot without contacting the init system

-w, --wtmp-only

Only write the wtmp shutdown entry, do not actually reboot

-d, --no-wtmp

Do not write a wtmp shutdown entry

-n, --no-sync

Do not sync hard disks before reboot

--no-wall

Do not send wall message before reboot

INSTALL

sudo apt install runit-init

CAVEATS

Using --force bypasses the init system and may result in data loss if filesystems are not properly synced. The systemctl command provides equivalent functionality with additional features.

HISTORY

reboot has been available since early Unix systems. On modern systemd-based systems, it is typically a symlink to systemctl.
