NAME

       lziprecover - recovers data from damaged lzip files

SYNOPSIS

       lziprecover [options] [files]

DESCRIPTION

       Lziprecover  is a data recovery tool and decompressor for files in the lzip compressed data format (.lz).
       Lziprecover is able to repair slightly damaged files (up to one single-byte error per member), produce  a
       correct file by merging the good parts of two or more damaged copies, reproduce a missing (zeroed) sector
       using a reference file, extract data from damaged files, decompress files, and test integrity of files.

       With the help of lziprecover, losing an entire archive just because of a corrupt byte near the  beginning
       is a thing of the past.

       Lziprecover  can  remove  the  damaged  members  from  multimember  files, for example multimember tar.lz
       archives.

       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.

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

       -q, --quiet
              suppress all messages

       -R, --repair

              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=<list>:d:t
              dump members listed/damaged, tdata to stdout

       --remove=<list>:d:t
              remove members, tdata from files in place

       --strip=<list>:d:t
              copy files to stdout stripping members given

       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...

       To extract all the files from archive 'foo.tar.lz', use the commands 'tar -xf foo.tar.lz' or 'lziprecover
       -cd foo.tar.lz | tar -xf -'.

       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  (e.g.,
       bug) which caused lziprecover to panic.
