SYNOPSISpdlzip [,options/] [,files/]
DESCRIPTIONPdlzip - A permissively licensed implementation of the lzip data compressor also able to decompress legacy lzma-alone (.lzma) files.
Lzma-alone is a very bad format; it is essentially a raw LZMA stream. If you keep any lzma-alone files, it is advisable to recompress them to lzip format. Lziprecover can convert lzma-alone files to lzip format without recompressing.
- -h, --help
- display this help and exit
- -V, --version
- output version information and exit
- -a, --trailing-error
- exit with error status if trailing data
- -c, --stdout
- write to standard output, keep input files
- -d, --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 
- -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)
- -1 .. -9
- set compression level [default 6]
- alias for -1
- alias for -9
If no file names are given, or if a file is '-', pdlzip 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 27 are interpreted as powers of two, meaning 2^12 to 2^27 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. 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 pdlzip to panic.
