SYNOPSIS

plzip [,options/] [,files/]

DESCRIPTION

Plzip - Parallel compressor compatible with lzip.

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

-B, --data-size=<bytes>

set size of input data blocks [2x8=16 MiB]

-c, --stdout

write to standard output, keep input files

-d, --decompress

decompress

-f, --force

overwrite existing output files

-F, --recompress

force re-compression of compressed files

-k, --keep

keep (don't delete) input files

-m, --match-length=<bytes>

set match length limit in bytes [36]

-n, --threads=<n>

set number of (de)compression threads [2]

-o, --output=<file>

if reading standard input, write to <file>

-q, --quiet

suppress all messages

-s, --dictionary-size=<bytes>

set dictionary size limit in bytes [8 MiB]

-t, --test

test compressed file integrity

-v, --verbose

be verbose (a 2nd -v gives more)

-0 .. -9

set compression level [default 6]

--fast

alias for -0

--best

alias for -9

If no file names are given, or if a file is '-', plzip compresses or 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... Dictionary sizes 12 to 29 are interpreted as powers of two, meaning 2^12 to 2^29 bytes.

The bidimensional parameter space of LZMA can't be mapped to a linear scale optimal for all files. If your files are large, very repetitive, etc, you may need to use the --dictionary-size and --match-length options directly to achieve optimal performance.

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 plzip to panic.
