$ curl -sL https://api.github.com/repos/mirror/busybox/tarball/master | busybox gzip | tar -xf - -C /tmp/foo tar: Archive is compressed. Use -z option tar: Error is not recoverable: exiting now $ curl -sL https://api.github.com/repos/mirror/busybox/tarball/master | busybox gzip | tar -xzf - -C /tmp/foo tar: This does not look like a tar archive tar: Skipping to next header tar: Exiting with failure status due to previous errors This is with GNU tar, how many different versions of tar did you try, anyway??? libarchive bsdtar works, which I guess means that libarchive permits you to wrap a tarball in *two* layers of gzip compression, then extract the contents. Personally, I would claim this is a buggy design goal, because you'd have to be nuts to create tarballs with multiple layers of recursive compression. -- Eli Schwartz Arch Linux Bug Wrangler and Trusted User
