xzdec

Small .xz and .lzma decompressors

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.
