shutil.copymode(src, dst, *, follow_symlinks=True)
Copy the permission bits from src to dst. The file contents, owner, and group are unaffected. src and dst are path names given as strings. If follow_symlinks is false, and both src and dst are symbolic links, copymode() will attempt to modify the mode of dst itself (rather than the file it points to). This functionality is not available on every platform; please see copystat() for more information. If copymode() cannot modify symbolic links
