ddrescuelog — tool for ddrescue mapfiles

Synopsis

ddrescuelog [options] mapfile

Description

GNU ddrescuelog - Tool for ddrescue mapfiles. Manipulates ddrescue mapfiles, shows their contents, converts them to/from other formats, compares them, and tests rescue status.

NOTE: In versions of ddrescue prior to 1.20 the mapfile was called 'logfile'. The format is the same; only the name has changed.

Options

-h, --help
display this help and exit
-V, --version
output version information and exit
-a, --change-types=<ot>,<nt>
change the block types of mapfile
-b, --block-size=<bytes>
block size in bytes [default 512]
-B, --binary-prefixes
show binary multipliers in numbers [SI]
-c, --create-mapfile[=<tt>]
create mapfile from list of blocks [+-]
-C, --complete-mapfile[=<t>]
complete mapfile adding blocks of type t [?]
-d, --delete-if-done
delete the mapfile if rescue is finished
-D, --done-status
return 0 if rescue is finished
-f, --force
overwrite existing output files
-i, --input-position=<bytes>
starting position of rescue domain [0]
-l, --list-blocks=<types>
print block numbers of given types (?*/-+)
-L, --loose-domain
accept an incomplete domain mapfile
-m, --domain-mapfile=<file>
restrict domain to finished blocks in file
-n, --invert-mapfile
invert block types (finished <--> others)
-o, --output-position=<bytes>
starting position in output file [ipos]
-p, --compare-mapfile=<file>
compare block types in domain of both files
-P, --compare-as-domain=<file>
like -p but compare finished blocks only
-q, --quiet
suppress all messages
-s, --size=<bytes>
maximum size of rescue domain to be processed
-t, --show-status
show a summary of mapfile contents
-v, --verbose
be verbose (a 2nd -v gives more)
-x, --xor-mapfile=<file>
XOR the finished blocks in file with mapfile
-y, --and-mapfile=<file>
AND the finished blocks in file with mapfile
-z, --or-mapfile=<file>
OR the finished blocks in file with mapfile

Use '-' to read a mapfile from standard input or to write the mapfile created by '--create-mapfile' to standard output. Numbers may be in decimal, hexadecimal or octal, and may be followed by a multiplier: s = sectors, k = 1000, Ki = 1024, M = 10^6, Mi = 2^20, etc...

Exit status: 0 for a normal exit, 1 for environmental problems (file not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or invalid input file, 3 for an internal consistency error (eg, bug) which caused ddrescuelog to panic.
