xzdec(1)

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.

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.

Free Books

The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.

Education

Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
