Besides using wdired, the obvious answer is to use `M'. However, in answering that, it becomes clear that the questioner does not know the UNIX command `chmod', and might not know about file and directory permissions. S?he might not even have what it takes locally to use `M-x man', to find out. And the doc for `M' - both the doc string and the Emacs manual, does not really explain `chmod' or what kind of input a user can type to the prompt from `M'. I think it would be helpful, for at least some users, to add some more explanation. In particular, it could explain about u, g, o, and a, and about the permissions fields rwx and their values.
