tar not preserving permissions?

BassKozz · 06-03-2009, 11:46 AM

I backed up using:

Code:

tar -cvpzf foo.tgz .

I restored using:

Code:

tar -C /home/user/restore/ -xvzf foo.tgz

and the permissions aren't kept, what gives?

When I try and run with -p on restore I get:

Code:

tar -C /home/user/restore/ -xvzfp foo.tgz
tar: p: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
tar: Child returned status 2
tar: /home/user/BACKUPS/foo.tgz: Not found in archive
tar: Error exit delayed from previous errors

p.s. I transfered the backup from one computer to another (different users).

Hello.

When you are extracting you are omitting the "p" option.

Hi

You need to use the p option in the extraction to preserve the archived permissions

Code:

tar -C /home/user/restore/ -xvpzf foo.tgz

Hope this helps, if not, please provide more detail about the permissions, owner and group settings for the files with

Code:

ls -l

.

Cheers

-f is the last. Whatever there is after that is supposed to be the file name.

That was it... {DOH}

Thanks i92guboj.

Interestingly enough "f" doesn't have to be last if you don't use a dash.

For Example:
tar xvfp foo.tgz = WORKS
tar -xvfp foo.tgz = DOES NOT WORK
tar -xvpf foo.tgz = WORKS

Wounder why that is?

From "tar.c" [GNU Tar 1.22]:

Code:

static void
decode_options (int argc, char **argv)
{
  /* -- code removed [noctilucent] -- */

  /* Convert old-style tar call by exploding option element and rearranging
     options accordingly.  */

  if (argc > 1 && argv[1][0] != '-')
    {

  /* -- code removed [noctilucent] -- */
