changing default shell

changing default shell

[Justin]

Hi,

I stopped using emacs for awhile and it seems I forgot a few things. 
Before, I remembered typing M-x to enter the name of a function which 
would allow me to modify certain environment variables for emacs. I'd 
enter the name of the function, hit enter, then emacs would ask for the 
variable name then a new buffer would open which would show the current 
value and allow me to graphically modify it. This buffer would also 
provide more information about the variable itself.

My end goal is to change the default shell to bash.

Thanks,
-Justin

If you mean environment variables per se, M-x setenv.  If you mean
options specific to Emacs, M-x customize-variable.

I don't know an emacs variable for this. I just use the environment variable:

    (setf (getenv "SHELL") "/usr/bin/clisp")

Hi Guys,

Thanks for the help. Yes, customize-variable was the one I was looking for.

I have cygwin installed on my windows xp system. I have used 
customize-variable to change the shell to C:/cygwin/bin/bash.exe

I clicked "Save for Future Sessions" and it put this in my ~/.emacs:

(custom-set-variables
   ;; custom-set-variables was added by Custom -- don't edit or 
cut/paste it!
   ;; Your init file should contain only one such instance.
  '(shell-file-name "C:/cygwin/bin/bash.exe"))
(custom-set-faces
   ;; custom-set-faces was added by Custom -- don't edit or cut/paste it!
   ;; Your init file should contain only one such instance.
  )


The problem is when I go: M-x shell it still uses the cripled ms command 
prompt.

Any suggestions?

I used this at one point... but I was using native ntemacs vs. cygwin
emacs.

Still... it might help.

(cond ((eq system-type 'windows-nt)
       (setq shell-file-name "bash")
       (setenv "PATH" (concat pal-cygwin-dir "/bin;" (getenv "PATH")))
       (setenv "SHELL" shell-file-name)
       (setq-default exec-path (cons (concat pal-cygwin-dir "/bin") exec-path)
                     explicit-sh-args '("-login" "-i")
                     process-coding-system-alist '(("bash" . undecided-unix)
                                                   ("ssh" . undecided-unix)))
       (add-hook 'shell-mode-hook
                 (lambda ()
                   (setq-default comint-scroll-show-maximum-output 'this
                                 comint-completion-addsuffix t
                                 comint-eol-on-send t
                                 w32-quote-process-args ?\")
                   (make-local-variable 'comint-completion-addsuffix)))

       (defun pal-comint-strip-ctrl-m (&optional string)
         "Strip trailing `^M' characters from the current output group."
         (interactive)
         (replace-regexp-in-string "" "" string nil nil nil))
       (add-hook 'comint-preoutput-filter-functions 'pal-comint-strip-ctrl-m)))

shell-file-name affects commands like `M-!' and `M-|'.
`C-h f shell RET' explains that you need to customize the
explicit-shell-file-name variable (or set the ESHELL or SHELL
environment variable).
