/usr/local/bin/lzma lzma (Lempel-Ziv-Markov chain-Algorithm) is an improved version of LZ77 compression algorithm. It was improved in way of maximum increasing of compression ratio, keeping high decompression speed and low memory requirements for decompressing. lzma command line tool has a similar interface to gzip and bzip2 and is intended to make use of LZMA compress.
