SUMMARY: Tar archives larger than 8GB

It was pointed out that the E flag applies to individual
files being archived.   So if you're archiving files that
are larger than 8GB, then the E flag is required.

There is no limit on the size of the archive itself.

Sincerest apologies for the hassle.  I should obviously
have read the man page more carefully.

And thanks to those who responded.

Subject: Tar archives larger than 8GB

In Solaris 10, is the E flag still mandatory when creating
tar archives over 8GB?

Using Solaris tar, we created a 14GB tar archive without using
the E flag for extended headers.

However tar didn't complain, and even without the E flag,
tar happily continued to create the archive even after it
exceeded 8GB.

We've untarred the 14GB archive and tested the files, and
everything seems to be fine.

So our question is:

   Is the E flag still mandatory when creating tar archives over 8GB?

Many thanks in advance for any replies.  I'll post a summary.
