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.
