/usr/share/doc/tar/NEWS :
version 1.13.16 - Paul Eggert, 1999-12-13.
* By default, tar now refuses to overwrite existing files when
extracting files from an archive; instead, it removes them before
extracting. There is one exception: existing nonempty directories
are not removed, nor are their ownerships or permissions extracted.
This fixes some longstanding security problems.
The new --overwrite option enables the old default behavior.
For regular files, tar implements this change by using the O_EXCL
option of `open' to ensure that it creates the file; if this fails, it
removes the file and tries again. This is similar to the behavior of
the --unlink-first option, but it is faster in the common case of
extracting a new directory.
Un tar xv --overwrite devrait donner le m�me r�sultats que les
versions pr�c�dentes.
