I used same syntex what you have written:
#tar -xvf httpd.conf /tmp/apache/

but it does not give any output in that location

Hi Deeos,

>> but it does not give any output in that location
Is it a empty tar file ?

Post the output of the "#tar -tvf httd.conf" command.
Lets see how many files the tar file has.

Murali

It's not the same syntax when you add things
to the command line. Especially when you
don't understand the command's syntax.

man tar

Perhaps because that's not how one specifies
a destination to "tar".

> #tar -tvf httd.conf

That was a pretty reasonable suggestion.
Perhaps you should try it.

"httpd.conf" is not a typical name for a
"tar" archive. Have you tried looking at the
file using something like a text editor?

What were you attempting to do with this syntax?
This will extract the directory tree /tmp/apache/, if it is on the archive.
But I'm not sure what that trailing "/" will do to it?

Around here, with HP "tar", it seems to
defeat the usual functionality:

dyi # tar tfv ta.tar
rwxr-xr-x 0/3 0 Jun 6 05:47 2010 /tmp/apache/
rw-r--r-- 0/3 5 Jun 6 05:47 2010 /tmp/apache/fred

dyi # tar xfv ta.tar /tmp/apache
x /tmp/apache/fred, 5 bytes, 1 tape blocks
dyi # tar xfv ta.tar /tmp/apache/
dyi #

(Interestingly, there's no mention of
"restoring" "/tmp/apache" itself.)

GNU "tar" does better with the "/":

dyi # gtar xfvP ta.tar /tmp/apache
/tmp/apache/
/tmp/apache/fred
dyi # gtar xfvP ta.tar /tmp/apache/
/tmp/apache/
/tmp/apache/fred

(And it does mention the directory itself.)

dyi # uname -a
HP-UX dyi B.11.31 U ia64 4235313755 unlimited-user license

dyi # gtar --version
tar (GNU tar) 1.22
[...]

What's "-P"?

Also interesting, possibly useful (to
someone):

dyi # pax -rv -f ta.tar /tmp/apache
USTAR format archive
/tmp/apache/
/tmp/apache/fred

dyi # pax -rv -f ta.tar /tmp/apache/
USTAR format archive
/tmp/apache/
dyi #
