[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 + --decompress --stdout (and possibly a few other commonly used options) + to decompress .xz files. lzmadec is identical to xzdec except that + lzmadec supports .lzma files instead of .xz files. + + To reduce the size of the executable, xzdec doesn't support multi- + threading or localization, and doesn't read options from XZ_OPT envi- + ronment variable. xzdec doesn't support displaying intermediate + progress information: sending SIGINFO to xzdec does nothing, but send- + ing SIGUSR1 terminates the process instead of displaying progress + information. + +OPTIONS + -d, --decompress, --uncompress + Ignored for xz(1) compatibility. xzdec supports only decompres- + sion. + + -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. + + -M limit, --memory=limit + Set the memory usage limit. If this option is specified multi- + ple times, the last one takes effect. The limit can be specified + in multiple ways: + + o The limit can be an absolute value in bytes. Using an integer + suffix like MiB can be useful. Example: --memory=80MiB + + o The limit can be specified as a percentage of physical RAM. + Example: --memory=70% + + o The limit can be reset back to its default value (currently + 40 % of physical RAM) by setting it to 0. + + o The memory usage limiting can be effectively disabled by set- + ting limit to max. This isn't recommended. It's usually bet- + ter to use, for example, --memory=90%. + + The current limit can be seen near the bottom of the output of + the --help option. + + -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 sta- + tus 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 + status 2 is not used by xzdec. + +NOTES + xzdec and lzmadec are not really that small. The size can be reduced + further by dropping features from liblzma at compile time, but that + shouldn't usually be done for executables distributed in typical non- + embedded operating system distributions. If you need a truly small .xz + decompressor, consider using XZ Embedded. + +SEE ALSO + xz(1) + + + +Tukaani 2009-06-04 XZDEC(1) |
