NAME

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

SYNOPSIS

dump.f2fs [ -i inode number ] [ -n NAT range ] [ -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.
-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.
