- Get the system device containing a path:
  `sudo grub-probe {{-t|--target}} device {{/boot/grub}}`
- Get GRUB disk name for a system device:
  `sudo grub-probe {{-t|--target}} drive {{/dev/sdX}} {{-d|--device}}`
- Get filesystem UUID:
  `sudo grub-probe {{-t|--target}} fs_uuid {{/boot/grub}}`
- Get filesystem label:
  `sudo grub-probe {{-t|--target}} fs_label {{/boot/grub}}`
- Get MBR partition type code(two hexadecimal digits):
  `sudo grub-probe {{-t|--target}} msdos_parttype {{/dev/sdX}}`
- Probe using a custom device map:
  `sudo grub-probe {{-t|--target}} drive {{/boot/grub}} {{-m|--device-map}} {{path/to/custom_device.map}}`
