or just use `cp --sparse=always` if it's from one file to another

  That is not so portable, so I recommend sticking with dd.

    Yup, `dd` helps in a lot of situations when you need portability, not just this one. Commands like `cp --sparse=always` aren't worth such a blanket disrecommendation though; if you are working directly at a console as opposed to scripting you typically don't need portability.

      Again, most of the consoles I work at don’t use GNU coretools.

        Then you obviously can't use this, but many people reading my suggestion can.
