A quick look at the docs <https://docs.python.org/3/library/shutil.html#shutil.move> shows what the OP is likely after.
The function has this signature: shutil.move(*src*, *dst*, *copy_function=copy2*)ΒΆ <https://docs.python.org/3/library/shutil.html#shutil.move> The copy_function argument is a function of two parameters (src and dst) which is called *when os.rename() cannot be used*. (E>g. for cross-filesystem moves.) In that case the individual files are copied using copy_function(src, dst). The default copy_function is shutil.copy2 <https://docs.python.org/3/library/shutil.html#shutil.copy2>, which defaults to follow_symlinks=True, i.e. it doesn't recognize symlinks and instead copies the contents. Given this context it's pretty clear that the OP wants a way to use shutil.copy2(src, dst, follow_symlinks=False), which preserves symlinks (if supported by the platform). Unfortunately we can't just add a new parameter follow_symlinks=True to shutil.move(), since that would break all existing code that passes a function of exactly two arguments. The OP's problem is easily solved using a lambda though: shutil.move(src, dst, lambda s, d: shutil.copy2(s, d, follow_symlinks=False)) On Thu, Dec 19, 2019 at 12:27 PM Steven D'Aprano <st...@pearwood.info> wrote: > On Wed, Dec 18, 2019 at 01:48:22PM -0000, Namjun Kim wrote: > > I think shutil.move method should provide a symlinks parameter. > > What will it do?
