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.

2024年4月8日 · 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.

When writing scripts that need to decompress files, it is recommended to always use the name xz with appropriate arguments (xz -d or xz -dc) instead of the names unxz and xzcat. DESCRIPTION xz is a general-purpose data compression tool with …

2024年7月29日 · XZ for Java aims to be a complete implementation of XZ data compression in pure Java.

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.

Initialize .xz Block encoder. Valid actions for lzma_code() are LZMA_RUN, LZMA_SYNC_FLUSH (only if the filter chain supports it), and LZMA_FINISH. The Block encoder encodes the Block Data, Block Padding, and Check value.

The .xz format supports multiple types of checks that are calculated from the uncompressed data. They vary in both speed and ability to detect errors.

Type of the delta calculation. Currently only byte-wise delta is supported. Other possible types could be, for example, delta of 16/32/64-bit little/big endian integers, but these are not currently planned since byte-wise delta is almost as good.

Here is a list of all documented struct and union fields with links to the struct/union documentation for each field:

Users of LZMA Utils should move to XZ Utils. XZ Utils support the legacy .lzma format used by LZMA Utils, and can also emulate the command line tools of LZMA Utils.
