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

-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.
