Hello Rob, Thank you again with your great support!
I come back with a different issue (it could be an intended behavior). If the archive contains a symlink that points outside of the archive, extracting it a second time will refuse to overwrite the symlink. Repro: rm -rf /tmp/foo; mkdir /tmp/foo > ln -sf /tmp/bar /tmp/foo/bar > /mnt/sdc/android/kernel/prebuilts/build-tools/path/linux-x86/tar czf > /tmp/foo.tar.gz -C /tmp/foo/ . > rm -rf /tmp/foo; mkdir /tmp/foo > /mnt/sdc/android/kernel/prebuilts/build-tools/path/linux-x86/tar xf > foo.tar.gz -C foo/ # This is okay > /mnt/sdc/android/kernel/prebuilts/build-tools/path/linux-x86/tar xf > foo.tar.gz -C foo/ # This is an error The content of the archive was: > $ /mnt/sdc/android/kernel/prebuilts/build-tools/path/linux-x86/tar tvf > foo.tar.gz > drwxr-xr-x elsk/primarygroup 0 2023-04-24 14:17 ./ > lrwxrwxrwx elsk/primarygroup 0 2023-04-24 14:17 ./bar -> /tmp/bar The second extraction generates the following error: > tar: './bar' /tmp/bar not under '/tmp/foo' > tar: had errors I was expecting that /tmp/foo/bar gets overwritten with the symlink. I guess it is because tar tries to dereference the symlink before writing the symlink, and it detects that it is writing outside of where it should be writing (which is good). Is this an intended behavior or a bug? On Tue, Apr 18, 2023 at 2:57 PM Yifan Hong <e...@google.com> wrote: > It works like a charm! Thanks!
