Shalom,

1. There is no new command, just tar. The old tar is probably still on the PATH variable. Make sure PATH is set so the new gnu tar is first or use it with its full path.

2. See the man page for gnu tar, but I've been told it works the same. HP ships a patch in the itrc patch database that enables its tar to make archives larger than 8 GB. That is why I never found the need to use gnu tar.

>Can you specify the patch ID to upgrade my tar

I think you can patch tar to go up to 8 Gb but no larger. To go larger you need pax(1):
PHCO_38835 11.31 pax(1) cumulative patch
PHCO_38165 11.23 Cumulative changes to pax(1)
PHCO_35998 11.11 pax(1) cumulative patch

Besides these patches, you need to download PAX-Enh from sofware.hp.com.

PHCO_36587 11.11 tar(1) cumulative patch
PHCO_39454 11.23 tar(1) catalogs ; directory timestamp

>by using this patch whether it's possible to take a backup of 18 GB using tar?

You can use tar if each file is smaller than 8 Gb. If files are > 8 Gb, you need pax.

How? Where?

So, which "tar" is that?

type tar

But you're not showing the error message, and
my psychic powers are too weak to tell me
what you saw.

Or GNU "tar". But installing GNU "tar" may
not help unless you actually _run_ GNU
"tar".

You guys sure are free and easy with this
"need" stuff. If there's some actual reason
that GNU "tar" would not work in this case,
please reveal it. Otherwise, please try to
remember that there is often more than one
way to solve a computer problem, so one
seldom _needs_ to do _any_ particular thing.
