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? -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns
