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.
