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

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

DESCRIPTION
       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.

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

       -I inode number
              Specify an inode number and scan full disk to dump out, include
              history inode block

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

       -M Block map
              Show all the allocated block addresses given inode number.

       -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.
