one minor nit, "The archive formats described in the EXTENDED DESCRIPTION section shall be automatically detected on input." so the ``-x format'' are not needed -- -x is actually not listed for the -r mode, at least at http://www.opengroup.org/onlinepubs/009695399/toc.htm so this would suffice pax -r -s ",^/,," < any_archive_the_implementation_groks I believe with ``-r -x format'' an implementation may treat input archive mismatch as an error, but this is not explicitly stated in the standard (this *may* be the only spot in the standard where I have a chance of knowing something Don doesn't) -- Glenn Fowler -- AT&T Research, Florham Park NJ --
