Ok, so now I know the mantra of don't use absolute pathes in Tar
files.  But I have one that I did that is and really need to restore it
to another directory.  Any ideas how I can do this?

Thanks.

I believe GNU tar can help you.  See http://www.veryComputer.com/

If it's in standard tar format use "star".

        ftp://ftp.fokus.gmd.de/pub/unix/star/

if it's in GNUtar format you may also use GNUtar.

But it cannot read standard tar archives :-(

the version I have, 1.12, says it
 "cannot read nor produce '--posix' archives"

but it seems able to read archives created by /bin/tar. Perhaps I'm
missing something?

        The simple way out of a problem like this is to
create whatever dir you need (temporarily), restore the file, move
it to it's final destination, and remember to use relative pathnames
next time.  Much faster than finding special progs, etc.

The point is that many tar files that are POSIX may be extracted by
GNU tar but not all of them. If you like a 90% solution, stay with
GNU tar otherwise you should use a program that is closer to the standard.

But if somebody likes to extract someting like /etc from another
machine you your method does not work.

I never use anything besides "star" if I have the choice. This is
anytime when I am not forced to do a "quick hack" (< 5 Minutes)
on a machine and then leave.

I agree that there is no good substitute for doing it right in the
first place.  However, it appears that chroot might be able to solve the
problem in the case in point, although it seems a lot of trouble.
(Admittedly chroot and gen-ing up temp directories, etc, etc)

Hi,

cd /directory

tar cvfp - | (cd /newdirectory ; tar xfp -)

If you do this with Sun's tar and not with "star" you have a high risk
of creating a disaster by killing all files > 10k.

star is safe because it does not overwrite recent files from the
archive.

If you use other tar's you should call

tar cvfp - | (cd /newdirectory && tar xfp -)

Or maybe also:

cd /newdirectory &&
tar cvfp - -C /directory . | tar xfp -

Thanks a lot. I have it note down.
