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

-A, –annotate-mapfile

add comments with human-readable pos/sizes

-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.
