Interface:

XZ Utils is free general-purpose data compression software with high compression ratio: compress a file about 30% smaller than gzip.

This software is distributed in two modes:
  • as compressed package that you have to download and manually install; if prerequisites are required, you will have to manually install them too;
  • as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.
Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.

Installation with rpm

This program is installable using the rpm package manager. See below for the install string. Required prerequisites are automatically processed by the package manager and, if needed, downloaded and installed.

XZ Utils Release Notes ====================== 5.2.3 (2016-12-30) * xz: - Always close a file before trying to delete it to avoid problems on some operating system and file system combinations. - Fixed copying of file timestamps on Windows. - Added experimental (disabled by default) sandbox support using Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL. * C99/C11 conformance fixes to liblzma. The issues affected at least some builds using link-time optimizations. * Fixed bugs in the rarely-used function lzma_index_dup(). * Use of external SHA-256 code is now disabled by default. It can still be enabled by passing --enable-external-sha256 to configure. The reasons to disable it by default (see INSTALL for more details): - Some OS-specific SHA-256 implementations conflict with OpenSSL and cause problems in programs that link against both liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0 are affected. - The internal SHA-256 is faster than the SHA-256 code in some operating systems. * Changed CPU core count detection to use sched_getaffinity() on GNU/Linux and GNU/kFreeBSD. * Fixes to the build-system and xz to make xz buildable even when encoders, decoders, or threading have been disabled from libilzma using configure options. These fixes added two new #defines to config.h: HAVE_ENCODERS and HAVE_DECODERS.

Manual installation

Program is distributed as ZIP package: download to temporary directory and unpack to destination folder, better if in PATH. See below for download link(s).

You can install the prerequisites with rpm running the following string in a command line:

yum install libc libcx libgcc1 libssp libstdc++6 libstdc++ libsupc++6 libsupc++ libgcc-fwd emxrt

XZ Utils (XZ archiver) v. 5.0.3 (20/12/2011, Paul Smedley (Smedles)) Readme/What's new
XZ Utils Release Notes ====================== 5.0.3 (2011-05-21) * liblzma fixes: - A memory leak was fixed. - lzma_stream_buffer_encode() no longer creates an empty .xz Block if encoding an empty buffer. Such an empty Block with LZMA2 data would trigger a bug in 5.0.1 and older (see the first bullet point in 5.0.2 notes). When releasing 5.0.2, I thought that no encoder creates this kind of files but I was wrong. - Validate function arguments better in a few functions. Most importantly, specifying an unsupported integrity check to lzma_stream_buffer_encode() no longer creates a corrupt .xz file. Probably no application tries to do that, so this shouldn't be a big problem in practice. - Document that lzma_block_buffer_encode(), lzma_easy_buffer_encode(), lzma_stream_encoder(), and lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK. - The return values of the _memusage() functions are now documented better. * Fix command name detection in xzgrep. xzegrep and xzfgrep now correctly use egrep and fgrep instead of grep. * French translation was added.
