NAME
xlunzip - test tool for the lzip_decompress linux module
SYNOPSIS
xlunzip [options] [files]
DESCRIPTION
Xlunzip is a test tool for the lzip decompression code of my lzip patch for linux. Xlunzip is similar to lunzip, but it uses the lzip_decompress linux module as a backend. Xlunzip tests the module for stream, buffer-to-buffer and mixed decompression modes, including in-place decompression (using the same buffer for input and output). You can use xlunzip to verify that the module produces correct results when decompressing single member files, multimember files, or the concatenation of two or more compressed files. Xlunzip can be used with unzcrash to test the robustness of the module to the decompression of corrupted data. Note that the in-place decompression of concatenated files can't be guaranteed to work because an arbitrarily low compression ratio of the last part of the data can be achieved by appending enough empty compressed members to a file.
OPTIONS
-h, --help display this help and exit -V, --version output version information and exit -c, --stdout write to standard output, keep input files -d, --decompress decompress (this is the default) -f, --force overwrite existing output files -I, --in-place decompress or test using only one buffer -k, --keep keep (don't delete) input files -o, --output=<file> if reading standard input, write to <file> -q, --quiet suppress all messages -t, --test test compressed file integrity -v, --verbose be verbose (a 2nd -v gives more) These options are ignored when --in-place is in effect: --insize[=<size>] pre-allocate and fill inbuf [default 16 KiB] --outsize[=<size>] pre-allocate outbuf [default 512 MiB] --nofill do not pass a fill function; requires --insize --noflush do not pass a flush function; requires --outsize If no file names are given, or if a file is '-', xlunzip 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 xlunzip to panic.
