How do I open a file for edit as root with Aquamacs?
aquamacs, emacs, macos, sudo
Solution
You can open a file as root using TRAMP (bundled with Emacs since version 22.1):
C-x C-f `/sudo:root@localhost:/path/to/file` RET
If you don't insert the `username@host` part, TRAMP defaults to `root@localhost` when using `/sudo`, so you can shorten the syntax to
C-x C-f `/sudo::/path/to/file` RET
Problem
I'm using Aquamacs to do most of my text editing, and would like to, selectively, open some files as root when editing them. Is there a way for me to open some files as root with Aquamacs (and not the rest)? I know that I can just start Aquamacs with a sudo command, but that's a bit too risky for me - I'd rather only have root permissions for editing files which absolutely require it.
