grub-probe
The program grub-probe
probes device information for a given path or device.
grub-probe --target=fs /boot/grub
grub-probe --target=drive --device /dev/sda1
grub-probe
must be given a path or device as a non-option argument.
Options
--help
Print a summary of the command-line options and exit.
--version
Print the version number of GRUB and exit.
-d, --device
If this option is given, then the non-option argument is a system device name (such as /dev/sda1
), and grub-probe
will print information about that device. If it is not given, then the non-option argument is a filesystem path (such as /boot/grub
), and grub-probe
will print information about the device containing that part of the filesystem.
-m file, --device-map=file
Use file as the device map rather than the default, usually /boot/grub/device.map
.
-t target, --target=target
Print information about the given path or device as defined by target. The available targets and their meanings are:
fs
- GRUB filesystem module.fs_uuid
- Filesystem Universally Unique Identifier (UUID).fs_label
- Filesystem label.drive
- GRUB device name.device
- System device name.partmap
- GRUB partition map module.abstraction
- GRUB abstraction module (e.g. ‘lvm’).cryptodisk_uuid
- Crypto device UUID.msdos_parttype
- MBR partition type code (two hexadecimal digits).hints_string
- A string of platform search hints suitable for passing to the search command.bios_hints
- Search hints for the PC BIOS platform.ieee1275_hints
-Search hints for the IEEE1275 platform.baremetal_hints
- Search hints for platforms where disks are addressed directly rather than via firmware.efi_hints
- Search hints for the EFI platform.arc_hints
- Search hints for the ARC platform.compatibility_hint
- A guess at a reasonable GRUB drive name for this device, which may be used as a fallback if the search command fails.disk
- System device name for the whole disk.
-v, --verbose
Print verbose messages.
