Command: lzma
LZMA (Lempel-Ziv-Markov chain-Algorithm) is an improved version of
famous LZ77 compression algorithm. It was improved in way of maximum
increasing of compression ratio, keeping high decompression speed and
low memory requirements for decompressing.
Syntax:
lzma.exe [flags and input files in any order]
Options:
-c --stdout Output to standard output.
-d --decompress Force decompression.
-z --compress Force compression.
-k --keep Keep (don't delete) input files.
-f --force Force overwrite of output file and compress
links.
-t --test Fest compressed file integrity.
-S .suf --suffix .suf Use suffix .suf on compressed files.
-q --quiet Suppress error messages.
-v --verbose Be verbose.
-h --help Print this message.
-L --license Display the license information.
-V --version Display the version numbers of LZMA SDK and
lzma.
-1 .. -2 Fast compression.
-3 .. -9 Good to excellent compression. -7 is the default.
--fast Alias for -1.
--best Alias for -9 (usually *not* what you want).
Memory usage depends a lot on the chosen compression mode -1 .. -9.
See the man page lzma(1) for details.
Comments:
LZMA, like most Zippers, has an extensive documentation that is beyond
