plzip [\,options\/] [\,files\/]


Plzip - Parallel compressor compatible with lzip.


-h, --help

display this help and exit

-V, --version

output version information and exit

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

set size of input data blocks, in bytes

-c, --stdout

send output to standard output

-d, --decompress


-f, --force

overwrite existing output files

-F, --recompress

force recompression 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)

-1 .. -9

set compression level [default 6]


alias for -1


alias for -9

If no file names are given, 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... 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 optimal performance. For example, -9m64 usually compresses executables more (and faster) than -9.

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.
