tar's uppercase J switch uses XZ (whereas the lowercase j switch uses bzip2). The XZ_OPT environment variable lets you set xz options. This is now maximal. See man xz for other options you can set (-e/--extreme might give you some additional compression benefit for some datasets). XZ_OPT=-e9 tar cJf tarfile.tar.xz directory

2013年9月17日 · xz -4e calls xz with the -4e compression option. (equal to -4--extreme) > filename.tar.xz directs the tarred and compressed file to filename.tar.xz; where -4e is, use your own compression options. I often use -k to --keep the original file and -9 for really heavy compression. -z to manually set xz to zip, though it defaults to zipping if not ...

Tools to compress/decompress xz and gzip files are also available on Windows systems, but are more commonly seen and used on UNIX systems. xz and 7zip are known to have a better compression algorithm than gzip, but use more memory and time to compress/decompress. This topic is nicely discussed here.

Xz copies almost all the defects of gzip and then adds some more, like the fragile variable-length integers. Just one bit-flip in bit 7 of any byte of one variable-length integer and the whole xz stream comes tumbling down like a house of cards. Using xz for anything other than compressing short-lived executables is not advisable.
