xzdec, lzmadec - Small .xz and .lzma decompressors


   xzdec [option...]  [file...]
   lzmadec [option...]  [file...]


   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.


   -d, --decompress, --uncompress
          Ignored   for   xz(1)   compatibility.    xzdec   supports  only

   -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.


   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.


   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.
