#1
sudo from within emacs
Posted by yaarg on Thu 1 Dec 2005 at 20:07
I've fallen in love with emacs recently, after taking the time to learn how to use properly and now I typically have emacs open for the entire time I'm using my computer. With Ion's app script, I simple need to press the windows key + e to jump to whether it may be.
One thing that I haven't found a solution for yet though, is how I edit a root owned file from an already open emacs? At the moment, I switch to an xterm and open it up with 'sudo vim' but it would be nice if there was a "open this next buffer with sudo" command?

One approach (if you allow root to SSH into your localhost) is to install "tramp". If you do that and place the following inside ~/.emacs then you can open files via SSH:
(require 'tramp) (setq tramp-default-method "ssh")
For example to open /etc/shadow you'd run:
C-x C-f /root@localhost:/etc/shadow
For more details look at the HTML files installed in /usr/share/doc/tramp.

Try: C-c C-f /su::/etc/passwd
This opens a file as root on the local host using 'su'. The alternative is available with /sudo::/etc/passwd, which uses sudo. See the tramp manual for more information

just note that this is different from xemacs;
C-x C-f /[su/]/path/to/file
and so forth. see the documentation for tramp.
