Both xz and 7-zip use lzma2 compression. But xz command line utility is very similar to gzip/bzip2, so most of the gzip options could be used. In fact tar has a filter also for xz which is 'J'. It can be used just like gzip tar cfJ something.tar.xz something (that is the same as, tar cf - something | xz > something.tar.gz) tar xfJ something.tar.xz
