寫了一個小函數,能夠以root權限從新打開當前的文件,相似sudo。 shell
(provide 'sudo) (defun sudo-reopen ( ) "reopen current file with sudo." ; (setq username (replace-regexp-in-string "\n" "" (shell-command-to-string "whoami"))) (setq sudo-file-real-path (replace-regexp-in-string "\n" "" (shell-command-to-string (concat "readlink -f " buffer-file-truename)) ) ) (kill-this-buffer) (find-file (concat "/sudo::" sudo-file-real-path)) (interactive) )
主要就是提供一個函數 sudo-reopen 以 /sudo::/path/to/file 的方式從新打開當前的文件。將上述代碼保存爲sudo.el後在 .emacs 中進行下面的配置: ide
(require 'sudo) (global-set-key (kbd "C-c s u") 'sudo-reopen)
