Apparently this is now automatically determined by the file name, but I still habitually add the flag. 30 years of muscle memory is hard to break!

If you add a for auto, it will choose the right compression based on the file name.
tar -caf foo.tar.xz foo
Will be an xz compressed tarball.
I tried it to check before making the comment. In Ubuntu 25.04 it does not automatically enable compression based on the filename. The automatic detection when extracting is based on file contents, not name.
