I know you can customize settings or set environmental variables to get emacs to use other shells in shell-mode (1, 2). Is it possible to simply start a shell specifying which shell you want to use interactively?

Like: M-x other-shell RET /path/to/csh RET

Or set up something in your init file to let you use other shells fairly easily without changing the default?

This appears to do the job:

(defun other-shell (explicit-shell-file-name)
  (interactive "f")
  (if (called-interactively-p)
      (call-interactively #'shell)
    (shell)))

This relies on shell using the variable explicit-shell-file-name as a first choice of the shell to be used.

It also relies on not using lexical scoping.

  • This works if you don't already have a shell running. But if you do, it switches you to the existing shell. – Tyler Apr 10 '16 at 20:09
  • @Tyler Use a prefix argument to avoid that. No different from the original shell command. – Harald Hanche-Olsen Apr 10 '16 at 20:10
  • To use a prefix when you have helm-M-x bound see this asnwer emacs.stackexchange.com/questions/20299/… – salotz Apr 12 '16 at 1:32
