Here’s a handy function that kills the current buffer and removes the file it is connected to.
(defun delete-this-buffer-and-file () "Removes file connected to current buffer and kills buffer." (interactive) (let ((filename (buffer-file-name)) (buffer (current-buffer)) (name (buffer-name))) (if (not (and filename (file-exists-p filename))) (error "Buffer '%s' is not visiting a file!" name) (when (yes-or-no-p "Are you sure you want to remove this file? ") (delete-file filename) (kill-buffer buffer) (message "File '%s' successfully removed" filename)))))
I bound C-c k to the function:
(global-set-key (kbd "C-c k") 'delete-this-buffer-and-file)
