Edit-file-as-root

I use emacs (or actually emacsclient -t) for sysadmin-type stuff, and in the course of doing so I often need to edit a file as root. So instead of opening up a second emacs instance as root, I wrote a little function that uses TRAMP to edit the file using its wonderful sudo: protocol.

(defun edit-file-as-root () (interactive) (let ((bfn buffer-file-name)) (kill-buffer) (find-file (concatenate 'string "/sudo:root@localhost:" bfn))))

Bind this to something convenient (say one of the F-keys) and you’re good to go.

So posting/editing posts from emacs seems to work.
