基于magnars版本，我修改如下，修复了INIT文件名部分:

(defun rename-current-buffer-file ()
  "Renames current buffer and file it is visiting."
  (interactive)
  (let* ((name (buffer-name))
        (filename (buffer-file-name))
        (basename (file-name-nondirectory filename)))
    (if (not (and filename (file-exists-p filename)))
        (error "Buffer '%s' is not visiting a file!" name)
      (let ((new-name (read-file-name "New name: " (file-name-directory filename) basename nil basename)))
        (if (get-buffer new-name)
            (error "A buffer named '%s' already exists!" new-name)
          (rename-file filename new-name 1)
          (rename-buffer new-name)
          (set-visited-file-name new-name)
          (set-buffer-modified-p nil)
          (message "File '%s' successfully renamed to '%s'"
                   name (file-name-nondirectory new-name)))))))

如果您正在使用Spacemacs，那么您可以免费获得这种行为，因为它附带了一个重命名-current-buffer-file的实现(基于magnars)，默认情况下绑定到src -f- r。

我知道这篇文章太老了，但在我找到的所有答案中，没有什么比Emacs在他们的教程中所说的更简单的了: M-x烘干(下水烘干) C-x C-q(在dired中切换为只读) 更改文件名，就像它只是文本文件中的一行一样: ::

  /home/okiw4n/Documents/project/light_script:
  total used in directory 20 available 339.2 GiB
  drwxr-xr-x. 2 okiw4n okiw4n 4096 Sep  7 09:07 .
  drwxr-xr-x. 3 okiw4n okiw4n 4096 Sep  4 10:03 ..
  -rw-r--r--. 1 okiw4n okiw4n 3594 Sep  7 08:39 explication.org
  -rw-r--r--. 1 okiw4n okiw4n   85 Sep  4 10:09 script.sh
  -rw-r--r--. 1 okiw4n okiw4n 3594 Sep  5 20:08 tuc.org~

后:

  /home/okiw4n/Documents/project/light_script:
  total used in directory 20 available 339.2 GiB
  drwxr-xr-x. 2 okiw4n okiw4n 4096 Sep  7 09:07 .
  drwxr-xr-x. 3 okiw4n okiw4n 4096 Sep  4 10:03 ..
  -rw-r--r--. 1 okiw4n okiw4n 3594 Sep  7 08:39 explication.org
  -rw-r--r--. 1 okiw4n okiw4n   85 Sep  4 10:09 script.sh
  -rw-r--r--. 1 okiw4n okiw4n 3594 Sep  5 20:08 TRUC.org~ (I have rewrite this file)

C-x C-s(保存更改) C-x C-k(终止缓冲区并返回到文件)。

有一个很简单的方法，你按下命令M-x，然后键入vc-rename-file，之后你只需要在目录中选择你当前的文件，然后选择新的名称。已更改文件的buff将被刷新。

基于magnars版本，我修改如下，修复了INIT文件名部分:

(defun rename-current-buffer-file ()
  "Renames current buffer and file it is visiting."
  (interactive)
  (let* ((name (buffer-name))
        (filename (buffer-file-name))
        (basename (file-name-nondirectory filename)))
    (if (not (and filename (file-exists-p filename)))
        (error "Buffer '%s' is not visiting a file!" name)
      (let ((new-name (read-file-name "New name: " (file-name-directory filename) basename nil basename)))
        (if (get-buffer new-name)
            (error "A buffer named '%s' already exists!" new-name)
          (rename-file filename new-name 1)
          (rename-buffer new-name)
          (set-visited-file-name new-name)
          (set-buffer-modified-p nil)
          (message "File '%s' successfully renamed to '%s'"
                   name (file-name-nondirectory new-name)))))))

我最喜欢的是来自Magnars (emacs岩石屏幕录制的名声)。

与其他选项不同的是，您不必从头输入名称—您可以获得要修改的当前名称。

(defun rename-current-buffer-file ()
  "Renames current buffer and file it is visiting."
  (interactive)
  (let* ((name (buffer-name))
        (filename (buffer-file-name))
        (basename (file-name-nondirectory filename)))
    (if (not (and filename (file-exists-p filename)))
        (error "Buffer '%s' is not visiting a file!" name)
      (let ((new-name (read-file-name "New name: " (file-name-directory filename) basename nil basename)))
        (if (get-buffer new-name)
            (error "A buffer named '%s' already exists!" new-name)
          (rename-file filename new-name 1)
          (rename-buffer new-name)
          (set-visited-file-name new-name)
          (set-buffer-modified-p nil)
          (message "File '%s' successfully renamed to '%s'"
                   name (file-name-nondirectory new-name)))))))
