Emacs: Batch Rename Files

To rename multiple files in emacs, the most easy way is:

1. Alt + x dired to go to the directory.
2. Alt + x dired-toggle-read-only 【Ctrl + x Ctrl + q】.
3. Then, just edit the file names. (You can use Alt + x query-replace or Alt + x query-replace-regexp [see Emacs: Find Replace in Current File] or rectangle commands. [see Emacs: Edit Column Text, Rectangle Commands])
4. When done, wdired-finish-edit 【Ctrl + c Ctrl + c】 to commit the changes.

To abort, Alt + x wdired-abort-changes 【Ctrl + c Ctrl + k】.
