There are buffers that prevent you from being able to execute interactive commands (by overriding the default M-x binding). For example, *ansi-term* buffer would do this.

(I know you can do C-cM-x to invoke the command).

Is there an existing way to rename a buffer that isn't the current buffer? (It's easy to write a function for it, but it seems like it should've been already written...)

  • As far as I know, there is no predefined command to rename a buffer other than the current one (e.g. read a buffer name). It's easy to define such a command, though.

  • @Drew Well, I guess, I'll have to accept that I have to write such a function.

  • You might want to wait a bit, to see if someone else provides info about this. I may be mistaken.

In case anyone is looking for a function that can rename a buffer that isn't the current buffer, here's one way to do it.

(defun rename-another-buffer (buffer new-name)
  "Rename a buffer that isn't the current buffer."
  (with-current-buffer buffer
    (rename-buffer new-name)))

It uses with-current-buffer to temporarily make the given buffer the current buffer so that rename-buffer can be used on it.

  • I would venture that the OP was looking for an interactive command, where you select a buffer to be renamed first interactively.
