NAME¶
Plzip - reduces the size of files
SYNOPSIS¶
plzip [
options] [
files]
DESCRIPTION¶
Plzip - A 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 input data block size in bytes
- -c, --stdout
- send output to standard output
- -d, --decompress
- 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 the number of (de)compression threads
- -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 [8MiB]
- -t, --test
- test compressed file integrity
- -v, --verbose
- be verbose (a 2nd -v gives more)
- -1 .. -9
- set compression level [default 6]
- --fast
- alias for -1
- --best
- 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.
