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.

       -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.
