XZDEC(1) XZ Utils XZDEC(1) NAME xzdec, lzmadec - Small .xz and .lzma decompressors SYNOPSIS xzdec [option...] [file...] lzmadec [option...] [file...] DESCRIPTION xzdec is a liblzma-based decompression-only tool for .xz (and only .xz) files. xzdec is intended to work as a drop-in replacement for xz(1) in the most common situations where a script has been written to use xz --decom- press --stdout (and possibly a few other commonly used options) to decom- press .xz files. lzmadec is identical to xzdec except that lzmadec sup- ports .lzma files instead of .xz files. To reduce the size of the executable, xzdec doesn't support multithreading or localization, and doesn't read options from XZ_DEFAULTS and XZ_OPT envi- ronment variables. xzdec doesn't support displaying intermediate progress information: sending SIGINFO to xzdec does nothing, but sending SIGUSR1 terminates the process instead of displaying progress information. OPTIONS -d, --decompress, --uncompress Ignored for xz(1) compatibility. xzdec supports only decompression. -k, --keep Ignored for xz(1) compatibility. xzdec never creates or removes any files. -c, --stdout, --to-stdout Ignored for xz(1) compatibility. xzdec always writes the decom- pressed data to standard output. -q, --quiet Specifying this once does nothing since xzdec never displays any warnings or notices. Specify this twice to suppress errors. -Q, --no-warn Ignored for xz(1) compatibility. xzdec never uses the exit status 2. -h, --help Display a help message and exit successfully. -V, --version Display the version number of xzdec and liblzma. EXIT STATUS 0 All was good. 1 An error occurred. xzdec doesn't have any warning messages like xz(1) has, thus the exit sta- tus 2 is not used by xzdec. NOTES Use xz(1) instead of xzdec or lzmadec for normal everyday use. xzdec or lzmadec are meant only for situations where it is important to have a smaller decompressor than the full-featured xz(1). xzdec and lzmadec are not really that small. The size can be reduced fur- ther by dropping features from liblzma at compile time, but that shouldn't usually be done for executables distributed in typical non-embedded operat- ing system distributions. If you need a truly small .xz decompressor, con- sider using XZ Embedded. SEE ALSO xz(1) XZ Embedded: <https://tukaani.org/xz/embedded.html> Tukaani 2024-04-08 XZDEC(1)
