grub2: Invoking grub2-probe

1 29 Invoking grub2-probe
1 ***********************
1 
1 The program 'grub2-probe' probes device information for a given path or
1 device.
1 
1      grub-probe --target=fs /boot/grub
1      grub-probe --target=drive --device /dev/sda1
1 
1    'grub2-probe' must be given a path or device as a non-option
1 argument, and also accepts the following options:
1 
1 '--help'
1      Print a summary of the command-line options and exit.
1 
1 '--version'
1      Print the version number of GRUB and exit.
1 
1 '-d'
1 '--device'
1      If this option is given, then the non-option argument is a system
1      device name (such as '/dev/sda1'), and 'grub2-probe' will print
1      information about that device.  If it is not given, then the
1      non-option argument is a filesystem path (such as '/boot/grub'),
1      and 'grub2-probe' will print information about the device
1      containing that part of the filesystem.
1 
1 '-m FILE'
1 '--device-map=FILE'
1      Use FILE as the device map (⇒Device map) rather than the
1      default, usually '/boot/grub2/device.map'.
1 
1 '-t TARGET'
1 '--target=TARGET'
1      Print information about the given path or device as defined by
1      TARGET.  The available targets and their meanings are:

1           MBR partition type code (two hexadecimal digits).
