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.
