XZ Utils (previously LZMA Utils) is a set of free command-line lossless data compressors, including LZMA and xz, for Unix-like operating systems and, from version 5.0 onwards, Microsoft Windows. XZ Utils consists of two major components: * xz, the command-line compressor and decompressor (analogous to gzip) * liblzma, a software library with an API similar to zlib Various command shortcuts exist, such as lzma (for xz --format=lzma), unxz (for xz --decompress; analogous to gunzip) and xzcat (for unxz --stdout; analogous to zcat)
