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.

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.
