NAME
plzip - reduces the size of files
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
-B, --data-size=<bytes>
set size of input data blocks [2x8=16 MiB]
-c, --stdout
send output to standard output
-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 stdin, place the output into <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, plzip compresses or decompresses from stan‐
dard input to standard output. Numbers may be followed by a multi‐
plier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024, M = 10^6, Mi =
2^20, G = 10^9, Gi = 2^30, etc... 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
--match-length and --dictionary-size options directly to achieve opti‐
mal 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.
