xz is a command line tool with syntax similar to that of gzip. xzdec is a decompression-only tool smaller than the full-featured xz tool. A set of shell scripts (xzgrep, xzdiff, etc.) have been adapted from gzip to ease viewing, grepping, and comparing compressed files.

Apr 8, 2024 · The .xz file format is a container format for compressed streams. There are no archiving capabilities, that is, the .xz format can hold only a single file just like the .gz and .bz2 file formats used by gzip and bzip2, respectively.

liblzma is part of XZ Utils https://tukaani.org/xz/. XZ Utils includes a gzip-like command line tool named xz and some other tools. XZ Utils is developed and maintained by Lasse Collin. Major parts of liblzma are based on code written by Igor Pavlov, specifically the LZMA SDK https://7-zip.org/sdk.html.

Jul 29, 2024 · XZ for Java aims to be a complete implementation of XZ data compression in pure Java.

XZ data compression support. Introduction. This aims to be a complete implementation of XZ data compression in pure Java. Features: Full support for the .xz file format specification version 1.2.1; Single-threaded streamed compression and decompression; Single-threaded decompression with limited random access support

Even when using BufferedInputStream, the performance tends to be worse (maybe 10-20 % slower) than with LZMA2InputStream or XZInputStream (when the .xz file contains LZMA2-compressed data).

This is the case when xz is run by a script or tool, for example, GNU tar(1): XZ_OPT=-2v tar caf foo.tar.xz foo Scripts may use XZ_OPT, for example, to set script-specific de- fault compression options.

The primary git repositories and released packages of the XZ projects are on GitHub. Constructive comments in issues and pull requests are welcome from anyone; one doesn’t need to be an existing contributor!

Creates a new XZ decompressor that decompresses exactly one XZ Stream from in without a memory usage limit.

XZ Embedded is a small decompressor for the .xz file format. It was developed with the Linux kernel in mind but it is easily usable in other projects too.
