(let ((default-directory "/sudo::")) (shell-command-to-string (string-join arguments " ")))) thank you. I will keep it for future considerations. I think it works slower as it invokes tramp and many other functions in background. Is there any practical benefit? I have tried using that function with (sudo "ls") and first I got the ~/tmp directory listing, then in second invokation, I got only "bin" listing, as it changed to default directory to be /root where I have "bin" only. My function would not change default-directory to /root -- maybe that is result of using default-directory, and it remains so maybe for the rest of tramp session. Try it out, it makes no sense to be changed. Your function that involves Tramp processes: (sudo "ls") → "admin_Leo babel-6KitXT babel-cyz28q babel-YJWc0L babel-ZlWVex" this is because I invoked editing of email message file in ~/tmp but on second invokation, without changing anything, few seconds thereafter: (sudo "ls") → "bin " (sudo "pwd") → "/root " This could be a bug, I do not know why should default directory be changed to "/root" if I am not root, but used /sudo:: (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)) (sudo "ls") → " 0install-ea1f1e-download 847cf980479cf1dd15482464efa8620ca98c1c93c5a3ac1e2a1dd24918b9cd46.html adb.1001.log ... and others in ~/tmp " Repeated (sudo "ls") shows same thing, without tramp. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns
