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. .PP The exit code returned by .B dump.f2fs is 0 on success and -1 on failure. .SH OPTIONS .TP .BI \-i " inode number" Specify an inode number to dump out. .TP .BI \-n " NAT range" Specify a range presented by nids to dump NAT entries. .TP .BI \-M " Block map" Show all the allocated block addresses given inode number. .TP .BI \-s " SIT range" Specify a range presented by segment numbers to dump SIT entries. .TP .BI \-a " SSA range" Specify a range presented by segment numbers to dump SSA entries. .TP .BI \-b " block address" Specify a block address to retrieve its metadata information. .TP .BI \-d " debug-level" Specify the level of debugging options. The default number is 0, which shows basic debugging messages. .TP .SH AUTHOR Initial checking code was written by Byoung Geun Kim . .SH AVAILABILITY .B dump.f2fs is available from git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-tools.git. .SH SEE ALSO .BR mkfs.f2fs(8), .BR fsck.f2fs(8), .BR defrag.f2fs(8), .BR resize.f2fs(8), .BR sload.f2fs(8).
