      And now you join the thousands of us who have heard of it but never have any use for it.

      Had you heard of cpio? I’m pretty sure I wouldn’t have heard of that either if it hadn’t been mentioned in a Unix book I bought in the 90s.

      I’d say pixz is considerably more interesting to improve tar.

      Used as a compressor with tar, it adds:

      • Parallel compression/decompression, increasingly important with many-core processors.

      • Indexed access. Tarballs, unlike, say, zip or 7zip, don’t normally support jumping right to the point in an archive where a file lives.

      It’s LZMA-based, like xz, lzip, or 7zip. Good-but-slow compression, faster decompression than bzip.
