NAME

6       ddrescuelog - tool for ddrescue mapfiles
7

SYNOPSIS

9       ddrescuelog [options] mapfile
10

DESCRIPTION

12       GNU  ddrescuelog  -  Tool  for ddrescue mapfiles.  Manipulates ddrescue
13       mapfiles, shows their contents, converts them  to/from  other  formats,
14       compares them, and tests rescue status.
15
16       NOTE:  In  versions  of  ddrescue  prior to 1.20 the mapfile was called
17       'logfile'. The format is the same; only the name has changed.

84              show a summary of mapfile contents
85
86       -v, --verbose

88
89       -x, --xor-mapfile=<file>
90              XOR the finished blocks in file with mapfile
91
92       -y, --and-mapfile=<file>

97
98       --shift
99              shift all block positions by (opos - ipos)
100
101       Use '-' to read a mapfile from standard input or to write  the  mapfile
102       created  by  '--create-mapfile'  to standard output.  Numbers may be in
103       decimal, hexadecimal or octal, and may be followed by a multiplier: s =
104       sectors, k = 1000, Ki = 1024, M = 10^6, Mi = 2^20, etc...
105
106       Exit  status:  0  for a normal exit, 1 for environmental problems (file
107       not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt  or
108       invalid input file, 3 for an internal consistency error (eg, bug) which
109       caused ddrescuelog to panic.
