The discussion of multiple-tape cpio archives prompted me to recommend afio, which defaults to writing cpio-compatible tape archives, but then it occurred to me that cpio would be unable to recognize an afio-created archive with more than one tape. And then i went to try to figure out how one would extract just one file from an afio-created archive, and realized that I don't know how! How does one do that? Seems like something i should be able to do... -- "For a successful technology, | Tom Betz - GBS - 914-375-1510 reality must take precedence over | tbetz@upaya.lilink.com public relations, for nature can |--------------------------------- not be fooled." - Richard Feynmann, Appendix F, _The_Challenger_Report_

Ake Sandgren was kind enough to direct me to the -y switch, which works, though not entirely consistently with the way other archiver programs work. For example, while 'afio -i -y "tbetz/progwork"' results in the contents of that directory being installed as desired, 'afio -i -y "tbetz/progwork/" does not work, nor does 'afio -i -y "tbetz/progwork/*". However, I now know how to use this feature, and only wonder that the only reply I received originated in Sweden!
