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.  Used in conjunction with
     `--extract' (`--get', `-x').  Extract files to standard output.
     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').
