      The user to whom the file should belong.  Argument can be a user name or a
      user ID.

      On Windows, a group (such as "Administrators") can be set as a file's owner
      and a user (such as "Administrator") can be set as a file's group; however,
      a file's owner and group shouldn't be the same. (If the owner is also
      the group, files with modes like `0640` will cause log churn, as they
      will always appear out of sync.)
