 Writing to Standard Output
 ..........................
 
 To write the extracted files to the standard output, instead of creating
 the files on the file system, use '--to-stdout' ('-O') in conjunction
 with '--extract' ('--get', '-x').  This option is useful if you are
 extracting files to send them through a pipe, and do not need to
 preserve them in the file system.  If you extract multiple members, they
 appear on standard output concatenated, in the order they are found in
 the archive.
 
 '--to-stdout'
 '-O'
      Writes files to the standard output.  Use only in conjunction with
      '--extract' ('--get', '-x').  When this option is used, instead of
      creating the files specified, 'tar' writes the contents of the
      files extracted to its standard output.  This may be useful if you
      are only extracting the files in order to send them through a pipe.
      This option is meaningless with '--list' ('-t').
 
    This can be useful, for example, if you have a tar archive containing
 a big file and don't want to store the file on disk before processing
 it.  You can use a command like this:
 
      tar -xOzf foo.tgz bigfile | process
 
    or even like this if you want to process the concatenation of the
 files:
 
      tar -xOzf foo.tgz bigfile1 bigfile2 | process
 
    However, '--to-command' may be more convenient for use with multiple
 files.  See the next section.
