NAME

       lziprecover - recovers data from damaged lzip files

SYNOPSIS

       lziprecover [options] [files]

DESCRIPTION

       Lziprecover - Data recovery tool and decompressor for the lzip format.

       Lziprecover can repair perfectly most files with small errors (up to one single-byte error
       per member), without the need of any extra redundance at all.  Losing  an  entire  archive
       just because of a corrupt byte near the beginning is a thing of the past.

       Lziprecover  can  also  produce  a  correct  file by merging the good parts of two or more
       damaged copies, extract data from damaged files, decompress files and  test  integrity  of
       files.

       Lziprecover  provides random access to the data in multimember files; it only decompresses
       the members containing the desired data.

       Lziprecover facilitates the management of metadata stored as trailing data in lzip files.

       Lziprecover is not a replacement for regular backups, but a last line of defense  for  the
       case where the backups are also damaged.

       -i, --ignore-errors
              make '--range-decompress' ignore data errors

       -k, --keep
              keep (don't delete) input files

       -l, --list
              print (un)compressed file sizes

       -m, --merge

       -o, --output=<file>
              place the output into <file>

       -q, --quiet
              suppress all messages

       -R, --repair
              try to repair a small error in file

       -s, --split
              split multimember file in single-member files

       -t, --test
              test compressed file integrity

       -v, --verbose
              be verbose (a 2nd -v gives more)

       --loose-trailing
              allow trailing data seeming corrupt header

       --dump-tdata
              dump trailing data to standard output

       --remove-tdata
              remove trailing data from files in place

       --strip-tdata
              copy files to stdout without trailing data

       If  no  file  names are given, or if a file is '-', lziprecover decompresses from standard
       input to standard output.  Numbers may be followed by a multiplier: k = kB = 10^3 =  1000,
       Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, 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 lziprecover to panic.
