I made myself M-x chmod below, to change the current visited file. I
usually just want to make a script executable. I know there's an
executable-chmod or something, but I can never remember and prefer
typing 755 or 700. The save-buffer is in case it's a new file.
(defun chmod (mode)
"Set the mode of the current file, as per the chmod program."
(interactive "sMode (3 or 4 octal digits): ")
(if (string-match "[0-3]?[0-7][0-7][0-7]" mode)
(progn
(unless (file-exists-p (buffer-file-name))
(save-buffer))
(set-file-modes (buffer-file-name) (string-to-number mode 8)))
(error "Invalid mode")))
