Hello, please allow for a short question as I'm not sure whether I'm encountering a bug or expected behaviour.
When extracting part of a TAR archive any directories and files given as arguments on the command line a restored with the correct meta information (uid/gid), but higher-level directories which are created implicitly don't receive the correct meta data. I have created a short testcase: linux:/tmp # mkdir -p foo/bar linux:/tmp # echo MyFile > foo/bar/myfile linux:/tmp # chown -R 5000:5000 foo linux:/tmp # find foo -ls 271257 4 drwxr-xr-x 3 5000 5000 4096 Sep 8 20:03 foo 271258 4 drwxr-xr-x 2 5000 5000 4096 Sep 8 20:03 foo/bar 271259 4 -rw-r--r-- 1 5000 5000 7 Sep 8 20:03 foo/bar/myfile linux:/tmp # tar cvfj foo.tar.bz2 foo foo/ foo/bar/ foo/bar/myfile linux:/tmp # rm -rf foo # remove original files/dirs linux:/tmp # tar xvfj foo.tar.bz2 foo/bar/myfile # extract single file foo/bar/myfile linux:/tmp # find foo -ls 271257 4 drwxr-xr-x 3 root root 4096 Sep 8 20:05 foo 271258 4 drwxr-xr-x 2 root root 4096 Sep 8 20:05 foo/bar 271259 4 -rw-r--r-- 1 5000 5000 7 Sep 8 20:03 foo/bar/myfile Only the file given on the command line, foo/bar/myfile, has been extracted, showing the correct uid/gid while foo and foo/bar do not. I suppose that this a consequence of creating the higher-level directories implicitly by TAR. Nevertheless it would desirable to restore part of a TAR archive having the meta information of higher-level directories set to the original values. If the behaviour shown is not a bug I would be thankful for a short tip on this issue.
