I use

tar -cJvf resultfile.tar.xz files_to_compress

to create tar.xz and

tar -xzvf resultfile.tar.xz

to extract the archive in current directory. How to use multi threading in both cases? I don't want to install any utilities.

tar -c -I 'xz -9 -T0' -f archive.tar.xz [list of files and folders]

  • Can you explain this answer with words? It’s not immediately clear to me what part enables multi threading. – SethMMorton Sep 7 at 18:56

    man xz -> -T – Artem S. Tashkinov Sep 7 at 19:23
  • tar -c = create a tar, -I 'xz -9 -T0' = use the compress program xz -9 -T0 (ultra, use as many threads as CPU cores), -f = write the tar to archive.tar.xz – ZiggyTheHamster Oct 14 at 1:40
  • On my TAR though, -I won't accept arguments, and expects a program only. Maybe you can make a simple shell script that is exec xz -9 -T0 $*? – ZiggyTheHamster Oct 14 at 1:51
  • This program is used for piping, so $* is redundant. Also, not sure why you want to use exec. – Artem S. Tashkinov Oct 14 at 9:39

For older tars, this works:

tar -cf -  list of files and folders| xz -9 -T0 >| archive.tar.T.xz
