NAME

       bootctl - Control the firmware and boot manager settings

SYNOPSIS

       bootctl [OPTIONS...] {COMMAND}

DESCRIPTION

       bootctl can check the EFI boot loader status, list available boot loaders and boot loader
       entries, and install, update, or remove the systemd-boot(7) boot loader on the current
       system.

OPTIONS

       The following options are understood:

       --path=
           Path to the EFI System Partition (ESP). If not specified, /efi, /boot, and /boot/efi
           are checked in turn. It is recommended to mount the ESP to /boot, if possible.

       -p, --print-path
           This option modifies the behaviour of status. Just print the path to the EFI System
           Partition (ESP) to standard output and exit.

       --no-variables
           Do not touch the firmware's boot loader list stored in EFI variables.

       --no-pager
           Do not pipe output into a pager.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

COMMANDS

       status
           Shows brief information about the system firmware, the boot loader that was used to
           boot the system, the boot loaders currently available in the ESP, the boot loaders
           listed in the firmware's list of boot loaders and the current default boot loader
           entry. If no command is specified, this is the implied default.

       install
           Installs systemd-boot into the EFI system partition. A copy of systemd-boot will be
           stored as the EFI default/fallback loader at ESP/EFI/BOOT/BOOT*.EFI. The boot loader
           is then added to the top of the firmware's boot loader list.

       update
           Updates all installed versions of systemd-boot(7), if the available version is newer
           than the version installed in the EFI system partition. This also includes the EFI
           default/fallback loader at ESP/EFI/BOOT/BOOT*.EFI. The boot loader is then added to
           end of the firmware's boot loader list if missing.

       remove
           Removes all installed versions of systemd-boot from the EFI system partition and the
           firmware's boot loader list.

       list
           Shows all available boot loader entries implementing the Boot Loader Specification[1],
           as well as any other entries discovered or automatically generated by the boot loader.

       set-default ID, set-oneshot ID
           Sets the default boot loader entry. Takes a single boot loader entry ID string as
           argument. The set-oneshot command will set the default entry only for the next boot,
           the set-default will set it persistently for all future boots.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.

ENVIRONMENT

       If $SYSTEMD_RELAX_ESP_CHECKS=1 is set the validation checks for the ESP are relaxed, and
       the path specified with --path= may refer to any kind of file system on any kind of
       partition.
