extundelete: invalid option -- 'h'
No action specified; implying --superblock.
extundelete: Missing device name.
Usage: extundelete [options] [--] device-file
Options:
--version, -[vV] Print version and exit successfully.
--help, Print this help and exit successfully.
--superblock Print contents of superblock in addition to the rest.
If no action is specified then this option is implied.
--journal Show content of journal.
--after dtime Only process entries deleted on or after 'dtime'.
--before dtime Only process entries deleted before 'dtime'.
Actions:
--inode ino Show info on inode 'ino'.
--block blk Show info on block 'blk'.
--restore-inode ino[,ino,...]
Restore the file(s) with known inode number 'ino'.
The restored files are created in ./RECOVERED_FILES
with their inode number as extension (ie, file.12345).
--restore-file 'path' Will restore file 'path'. 'path' is relative to root
of the partition and does not start with a '/'
The restored file is created in the current
directory as 'RECOVERED_FILES/path'.
--restore-files 'path' Will restore files which are listed in the file 'path'.
Each filename should be in the same format as an option
to --restore-file, and there should be one per line.
--restore-directory 'path'
Will restore directory 'path'. 'path' is relative to the
root directory of the file system. The restored
directory is created in the output directory as 'path'.
--restore-all Attempts to restore everything.
-j journal Reads an external journal from the named file.
-b blocknumber Uses the backup superblock at blocknumber when opening
the file system.
-B blocksize Uses blocksize as the block size when opening the file
system. The number should be the number of bytes.
--log 0 Make the program silent.
--log filename Logs all messages to filename.
--log D1=0,D2=filename Custom control of log messages with comma-separated
Examples below: list of options. Dn must be one of info, warn, or
--log info,error error. Omission of the '=name' results in messages
--log warn=0 with the specified level to be logged to the console.
--log error=filename If the parameter is '=0', logging for the specified
level will be turned off. If the parameter is
'=filename', messages with that level will be written
to filename.
-o directory Save the recovered files to the named directory.
The restored files are created in a directory
named 'RECOVERED_FILES/' by default.

NOTICE: Extended attributes are not restored.
WARNING: EXT3_FEATURE_INCOMPAT_RECOVER is set.
The partition should be unmounted to undelete any files without further data loss.
If the partition is not currently mounted, this message indicates
it was improperly unmounted, and you should run fsck before continuing.
If you decide to continue, extundelete may overwrite some of the deleted
files and make recovering those files impossible. You should unmount the
file system and check it with fsck before using extundelete.
Would you like to continue? (y/n)
