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 --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 multithreading or localization, and doesn't read options from XZ_DEFAULTS and
       XZ_OPT environment 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 decompressed 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 status 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 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.
