NAME
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
-pbut 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
-vgives 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.
