Compresser un fichier de grande taille en plusieurs fichiers xz de taille limitée

J'ai des fichiers de taille 28Go.

Je veux compresser en utilisant .xz LZMA, avec des fichiers de taille 1G (1024Mo) en .xz...

MyFile.vdi -> MyFile00.xz, MyFile01.xz, MyFile02.xz...

Comment faire sur macOS?

ÉDITION

sh-3.2# xz -ek9vfc Centos\ 7\ 1511\ 64bits_20170629\(avec_dukto\).vdi

UTILISATION

# xz -ek9vfc Centos\ 7\ 1511\ 64bits_20170629\(avec_dukto\).vdi

# xz -e9vfc < Centos\ 7\ 1511\ 64bits_20170629\(avec_dukto\).vdi | split -b 1024m - Centos\ 7\ 1511\ 64bits_20170629\(avec_dukto\).vdi.xz

Voici la sortie.

# ls -al Centos\ 7\ 1511\ 64bits_20170629\(avec_dukto\).vdi*

Compress or decompress FILEs in the .xz format.

  -z, --compress      force compression
  -d, --decompress    force decompression
  -t, --test          test compressed file integrity
  -l, --list          list information about .xz files
  -k, --keep          keep (don't delete) input files
  -f, --force         force overwrite of output file and (de)compress links
  -c, --stdout        write to standard output and don't delete input files
  -0 ... -9           compression preset; default is 6; take compressor *and*
                      decompressor memory usage into account before using 7-9!
  -e, --extreme       try to improve compression ratio by using more CPU time;
                      does not affect decompressor memory requirements
  -T, --threads=NUM   use at most NUM threads; the default is 1; set to 0
                      to use as many threads as there are processor cores
  -q, --quiet         suppress warnings; specify twice to suppress errors too
  -v, --verbose       be verbose; specify twice for even more verbose
