xz --version

Dependencies: +bzip2,+gettext,+grep,+tar

To un-pack (extract) files with the extension .tar.xz (or .txz), enter into the command-line interface (upper-case J option, not lower-case j option):
tar xfJv [file...]

To decompress (extract) a file or directory with the extension .xz:
xz -d [file...] [dir...]

To compress a file or directory with xz compression:
xz [file...] [dir...]

To create an archive of a directory with xz compression:
tar cfJv file.tar.xz [dir...]
