Project home page: http://tukaani.org/xz/

Xz compression creates:

• 30% smaller output than gzip compression
• 15% smaller output than bzip2 compression

Archive file management

• Extract (un-pack) an archive, with file extension tar.xz (upper-case J option, not lower-case j option):
  

  tar xfJv [existing_archive_file...]

• Create an archive, with file extension tar.xz, of a directory with maximum xz compression:
  

  XZ_OPT=9e tar cfJv new_archive_file.tar.xz [dir...]

Non-archive file management

• Decompress (extract) a file that has xz compression:
  

  xz -d [file...]

• Compress a file with xz compression:
  

  xz [file...]
