CentOS - Jun 2010 - tar cvhf with link restore??

I am doing "tar" test due to some software require "tar
cvhf".  When I using "tar cvhf and tar xvhf ", files have
symbolic link replace by physical files.

wield things is my friend using same command 'tar cvhf and tar xvhf". 
after restore link still there.

does there has way when I using "tar cvhf" and "tar xvhf" I
can get link back not physical files?

O.S. is CENTOS 5.4 and 5.5.

Thanks.

	I find it unlikely he's using the same command line; see below.

	-h / --dereference does not archive / follow the link but
	rather the file that the link points to; it dereferences it
	during archive creation.

	Simple answer: do not use -h / --dereference and you will have
	the behavior you wish.

	As always, "man tar" for more information.

I understand what you said.  In theory "h" should replace link to
physical file.  But it really happen.
