Unlink First
............

`--unlink-first'
`-U'
     Remove files before extracting over them.  This can make `tar' run
     a bit faster if you know in advance that the extracted files all
     need to be removed.  Normally this option slows `tar' down
     slightly, so it is disabled by default.
