DDRESCUELOG(1) User Commands DDRESCUELOG(1) NAME ddrescuelog - tool for ddrescue mapfiles SYNOPSIS ddrescuelog [options] mapfile DESCRIPTION GNU ddrescuelog is a tool that manipulates ddrescue mapfiles, shows mapfile contents, converts mapfiles to/from other formats, compares mapfiles, tests rescue status, and can delete a mapfile if the rescue is done. Ddrescuelog operations can be restricted to one or several parts of the mapfile if the domain setting options are used. Use a hyphen '-' as mapfile to read the mapfile from standard input (also in the options taking a mapfile argument) or to write the mapfile created by '--create-mapfile' to standard output. NOTE: In versions of ddrescue prior to 1.20 the mapfile was called 'log- file'. 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 -A, --annotate-mapfile add comments with human-readable pos/sizes -b, --block-size=<bytes> block (sector) 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 -F, --format=<name> format for -c and -l (list, bitmap-[bl]e) -i, --input-position=<bytes> starting position of rescue domain [0] -l, --list-blocks=<types> print block numbers of given types (?*/-+) -L, --loose-domain accept unordered domain mapfile with gaps -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 --shift shift all block positions by (opos - ipos) 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 command line options, I/O errors, etc), 2 to indicate a cor- rupt or invalid input file, 3 for an internal consistency error (e.g., bug) which caused ddrescuelog to panic.
