By Xah Lee. Date: . Last updated: .

Here's emacs commands that delete the current file.

(defun xah-delete-current-file-make-backup ()
  "Delete current file, makes a backup~, close the buffer.
If buffer is not a file, copy content to `kill-ring', delete buffer.
If buffer is a file, the file's directory is shown with cursor at the next file.

Backup filename is “‹name›~‹dateTimeStamp›~”. Existing file of the same name is overwritten. If buffer is not a file, the backup file name starts with “xx_”.

Call `xah-open-last-closed' to open the backup file.
