systemctl-reboot

Restart the system

TLDR

Reboot the system

$ systemctl reboot

Reboot into firmware setup

$ systemctl reboot --firmware-setup

Force immediate reboot

$ systemctl reboot -f

Reboot into a specific boot loader entry once

$ systemctl reboot --boot-loader-entry=[entry_id]

Schedule reboot at a specific time

$ systemctl reboot --when=+30min

systemctl reboot restarts the system, gracefully stopping all services and unmounting filesystems before initiating a hardware reset.The --firmware-setup option sets an EFI variable that tells the firmware to enter setup mode on next boot, useful for accessing UEFI settings without needing to press a key at the right time.

PARAMETERS

-f, --force

Skip graceful service shutdown

--force --force (-ff)

Immediate reboot without cleanup (dangerous)

--firmware-setup

Reboot into BIOS/UEFI firmware setup menu

--no-wall

Don't send wall message to users

--boot-loader-menu= TIMEOUT

Reboot into the boot loader menu, showing it for the specified timeout

--boot-loader-entry= ID

Reboot into a specific boot loader entry once (use `--boot-loader-entry=help` to list entries)

--when= TIMESTAMP

Schedule reboot at a specific time (use `--when=cancel` to cancel a scheduled reboot)

INSTALL

sudo apt install systemd

sudo dnf install systemd

sudo pacman -S systemd

sudo zypper install systemd

brew install systemd

nix profile install nixpkgs#systemd

CAVEATS

Force mode can cause data loss. Firmware setup support depends on UEFI implementation. Some systems may not support the firmware-setup flag.

HISTORY

The reboot subcommand integrates with systemd's shutdown infrastructure, providing scheduled reboots and firmware setup access that traditional reboot commands lacked.
