Are there differences between the 'tar' facilities supported
by AT&T System V Unix and BSD Unix?
Here at the AECOM Dept. of Biochemistry, we just acquired a
Silicon Graphics 80 which runs System V Unix. However, the
man pages for 'tar' indicate that the version used on the
Silicon Graphics machine is from Berkeley.
We are attempting to 'port over some source code (yes, it's licensed)
from a VAX 780 also running System V. However, every time we
unpack a tar archive prepared on the VAX 780 with the SG 80,
it unpacks correctly. Files get truncated, checksum errors appear,
multiple files in one archive aren't recognized, etc.
Any help is greatly appreciated...

Here are a few additional facts to help you wizards...
With the archive written by BSD tar, there are extra characters
in the padding to 'flesh' out the current block that apparently
follow the end of the file at a fixed distance. Perhaps these
are related to how many files there are and how big they are?
Can I get the System V machine to write these characters at the
end of the files in the archive it creates?
If not, can I edit the current archive created with System V tar
to include these characters so that it is recognized by the BSD
tar? This would probably be worth my time, since moving 6 Megabyte
archives by phone line is painful process I'd hate to have to repeat.

I have created tar files under 4.3BSD on a vax and had no trouble reading them on SYSV R3 on an AT&T 3b2, and vice-versa, so there shouldn't be any difference between tar files on either system.
