cpio large files

[h . b . j . ensing]

Hello Orion,

Thanks for your reaction and the reading hints. I will dive into it.

I will also send this mail to <help-gnu-utils@gnu.org> as you suggested.
Maybe someone will pick this up and kindly provide me with some answers.

Meanwhile I've got a new version of (g)cpio working for Compaq Tru-64, HP-UX
and Sun Solaris.
Especially Solaris posed a big problem because of the 'long long' data type,
but I solved it.

I have introduced a new option '-HBIG' and a corresponding header-format
'070708'.
Theoretically this should work with files up to 218 TB in size. We have
succesfully tested it with files of 11 GB.

If you have any remarks about the above please let me know.
One last question: how should I go about with the version numbering? The
current version is (as you will probably know) 2.4.2. How should I name it
after my changes? 2.5.0? 2.4.3? 2.4.2B? Any ideas?

Regards,

Try sending this question to <help-gnu-utils@gnu.org>.  I don't know
the answer.

You don't have to, but if cpio does not have this functionality then
certainly many other people want it, and you would save others the
time that you spend in implementing it.  Please read some about our
philosophy on our philosophy page
(http://www.gnu.org/philosophy/philosophy.html).  In particular, I
recommend:

Good luck and happy hacking!
