XZ 5.2 5 FREE

The xz format improves on lzma by allowing for preprocessing filters. The number of threads can be less than defined if the file is not big enough for threading with the given settings or if using more threads would exceed the memory usage limit. Threaded decompression requires multiple compressed blocks within a stream which are created by the threaded compression interface. since version 5.4.0 threaded decompression has been implemented. Xz has supported multi-threaded compression (with the -T flag) since 2014, version 5.2.0. Tar xJf keep.txz # decompress then extract the file.

XZ 5.2 5 ARCHIVE

Tar cJf keep.txz keep # archive then compress the directory. Single-letter tar example for archive with compress and decompress with extract using short suffix: Tar -x -lzma -f my_ # results in /some_directory Tar -x -xz -f my_ # results in /some_directory Tar -c -lzma -f my_ /some_directory # results in my_ĭecompressing the archive and extracting its contents: Tar -c -xz -f my_ /some_directory # results in my_ Version 1.22 or greater of the GNU implementation of tar has transparent support for tarballs compressed with lzma and xz, using the switches -xz or -J for xz compression, and -lzma for LZMA compression. They cannot bundle multiple files into a single archive – to do this an archiving program is used first, such as tar. Just like gzip and bzip, xz and lzma can only compress single files (or data streams) as input.

XZ Utils can compress and decompress both the xz and lzma file formats, but since the LZMA format is now legacy, XZ Utils compresses by default to xz.īoth the behavior of the software as well as the properties of the file format have been designed to work similarly to those of the popular Unix compressing tools gzip and bzip2. 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) liblzma, a software library with an API similar to zlib.xz, the command-line compressor and decompressor (analogous to gzip).XZ Utils consists of two major components: Compression can be much slower than gzip, and is slower than bzip2 for high levels of compression, and is most useful when a compressed file will be used many times. Decompression speed is higher than bzip2, but lower than gzip. In most cases, xz achieves higher compression rates than alternatives like gzip and bzip2. XZ Utils started as a Unix port of Igor Pavlov's LZMA- SDK that has been adapted to fit seamlessly into Unix environments and their usual structure and behavior. For compression/decompression the Lempel–Ziv–Markov chain algorithm (LZMA) is used.

XZ Utils (previously LZMA Utils) is a set of free software command-line lossless data compressors, including the programs lzma and xz, for Unix-like operating systems and, from version 5.0 onwards, Microsoft Windows.
