       --overwrite
              Overwrite existing files when extracting.

       --overwrite-dir
              Overwrite metadata of existing directories when extracting (default).

       --recursive-unlink
              Recursively remove all files in the directory prior to extracting it.

       --remove-files
              Remove files from disk after adding them to the archive.

       --skip-old-files
              Don’t replace existing files when extracting, silently skip over them.

       -U, --unlink-first
              Remove each file prior to extracting over it.

       -W, --verify
              Verify the archive after writing it.

   Output stream selection
       --ignore-command-error

              Extract files to standard output.

       --to-command=COMMAND
              Pipe  extracted files to COMMAND.  The argument is the pathname of an external program, optionally with command line arguments.  The program will be invoked and the contents of the file being extracted supplied
              to it on its standard input.  Additional data will be supplied via the following environment variables:

              TAR_FILETYPE
                     Type of the file. It is a single letter with the following meaning:
