       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_OPT
       environment variable.  xzdec doesn’t  support  displaying  intermediate
       progress  information:  sending  SIGINFO  to  xzdec  does  nothing, but
       sending SIGUSR1 terminates the process instead of  displaying  progress


       -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.

       -M limit, --memory=limit
              Set the  memory  usage  limit.   If  this  option  is  specified
              multiple  times,  the  last  one  takes effect. The limit can be
              specified in multiple ways:

              ·  The limit can be an absolute value in bytes. Using an integer
                 suffix like MiB can be useful. Example: --memory=80MiB

              ·  The  limit  can be specified as a percentage of physical RAM.
                 Example: --memory=70%

              ·  The limit can be reset back to its default value  by  setting
                 it to 0.

              ·  The  memory  usage  limiting  can  be effectively disabled by
                 setting limit to max.  This isn’t recommended.  It’s  usually
                 better 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
              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.


       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.
