Re: Mac terminal.app: starting emacs, possibly as sudo

[Marius Hofert]

Dear Perry, Dear Peter,

thanks a lot for helping.

I tried sudo /Applications/Emacs.app/Contents/MacOS/bin/emacs and I am indeed 
root in the shell :-) 
There are some things that are strange, though: Option/Alt is not Meta anymore, 
so when I wanted to start a shell with M-x ... I obtained a "=" symbol (or 
rather, an "approximate" symbol). I realized that ESC is now Meta. 
=> Are there any other significant changes I should be aware of?
=> Is it possible to get the same/similar behavior as in the GUI, maybe through 
simply redefining root's .emacs and .emacs.d as my own? (bad practice?)

Well, maybe I should rethink the whole process: When do I want to open emacs as 
root? From time to time, I open a file and modify it. When I try to save it, I 
get the read-only warning. This means I would like to be su to modify this 
file. It's probably best to just open it with C-x C-f /sudo::path-to-file... 
But by closing and reopening all my modifications to the file are lost. How can 
one avoid this?


Cheers,

Marius
