(defun sudo (&rest arguments)
"Executes list ARGUMENTS with system command `sudo'."
(let ((default-directory
(concat "/sudo::" (file-local-name (expand-file-name default-directory)))))
(shell-command-to-string (string-join arguments " "))))
(sudo "ls") → " 0install-ea1f1e-download
847cf980479cf1dd15482464efa8620ca98c1c93c5a3ac1e2a1dd24918b9cd46.html
adb.1001.log
..."
(sudo "ls") → " 0install-ea1f1e-download
847cf980479cf1dd15482464efa8620ca98c1c93c5a3ac1e2a1dd24918b9cd46.html
adb.1001.log
..."
That one works well. I will keep it.
On the other hand, now I have got concern for this command:
(defun sudo (arguments)
"Executes list ARGUMENTS with system command `sudo'."
(let* ((command (format "sudo su -c -- root -c \"%s\"" (string-join (list arguments))))
(return (shell-command-to-string command)))
return))
As I would not like, definitely I would not like executing my sudo
commands on remote servers which I use so often with the above sudo
command.
So I would like to make sure I am on the local file system, as if I am
on /sudo:: file system or /ssh: or similar, that is not something I
would like. I have multiple notebooks which I access, imagine I change
default directory to some remote one and I am not visible in the
buffer of Dired. This happens sometimes. Then I wish to execute fan
control, but it would run on remote computer.
How to check if default directory is on local file system?
