lziprecover: recovers data from damaged lzip files

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

OPTIONS

-h, --help

display this help and exit

-V, --version

output version information and exit

-a, --trailing-error

exit with error status if trailing data

-A, --alone-to-lz

convert lzma-alone files to lzip format

-c, --stdout

write to standard output, keep input files

-d, --decompress

decompress

-D, --range-decompress=<range>

decompress a range of bytes (N-M) to stdout

-f, --force

overwrite existing output files

-i, --ignore-errors

make '--range-decompress' ignore data errors

-k, --keep

keep (don't delete) input files

-l, --list

print total file sizes and ratios

-m, --merge

correct errors in file using several copies

-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)

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.
