How about having tar autodetect lz4 compression, so that tar xf foo.tar.lz4 etc. works? https://github.com/lz4/lz4
Evidently the magic number is the four bytes 0x04 0x22 0x4d 0x18 (except it's endian-dependent? Seems crazy, but not sure) https://en.wikipedia.org/wiki/LZ4_(compression_algorithm) -> https://github.com/lz4/lz4/blob/dev/doc/lz4_Frame_format.md For your consideration. Sorry if already discussed. --thanks, karl.
