       dump.f2fs - retrieve directory and file entries from an F2FS-formated image


       dump.f2fs  [  -i  inode  number  ] [ -n NAT range ] [ -s SIT range ] [ -a SSA range ] [ -b
       block address ] [ -d debugging-level ] device


       dump.f2fs is used to retrieve f2fs metadata (usually in a disk partition).  device is  the
       special file corresponding to the device (e.g.  /dev/sdXX).

       Currently,  it  can retrieve 1) a file given its inode number, 2) NAT entries into a file,
       3) SIT entries into a file, 4) SSA entries into a file, 5) reverse  information  from  the
       given block address.

       The exit code returned by dump.f2fs is 0 on success and -1 on failure.


       -i inode number
              Specify an inode number to dump out.

       -n NAT range
              Specify a range presented by nids to dump NAT entries.

       -s SIT range
              Specify a range presented by segment numbers to dump SIT entries.

       -a SSA range
              Specify a range presented by segment numbers to dump SSA entries.

       -b block address
              Specify a block address to retrieve its metadata information.

       -d debug-level
              Specify the level of debugging options.  The default number is 0, which shows basic
              debugging messages.
