yet another rookie question M-x shell

[billy]

I have no problem getting a shell to work.
How do I get more than one shell available?
M-x returns me to the same shell each time.

Maybe adjusting same-window-buffer-names variable (C-h v...) can also help?

M-x rename-buffer

name the old shell something else... a good idea would be to name it
something related to what you feel you need it for i.e. "rootshell" or
"compilation shell" or  "this is a shell that I want because I want to
litter my buffer list with lots o' stuff".

Then, after you rename the original shell, you type this command:

M-x shell

and you will have another shell.

Remember, emacs helps those who help themselves.  You might find these
commands useful:

C-h i - this will bring you to the top level of your info docs.  Then,
if you browse or hit C-s you can search for appropriate items.

M-x man - while not emacs specific, and not ideal for looking for emacs
documentation, I feel that emacs might not be the only thing that you
might need documentation on.

M-x apropos
C-h f <function-name>
C-h v <variable-name>

These are more advanced topics and you should look them up.  While not
necessarily useful at this juncture in your education, they will be
helpful later.

The documentation for emacs is quite good.  Become familiar with it.

,----[ C-h f shell RET ]
| shell is an interactive compiled Lisp function in `shell'.
| (shell &optional BUFFER)
|
| Run an inferior shell, with I/O through BUFFER (which defaults to 
`*shell*').
| Interactively, a prefix arg means to prompt for BUFFER.
| If BUFFER exists but shell process is not running, make new shell.

The sentence above means `C-u M-x shell RET' does what you want.

| If BUFFER exists and shell process is running, just switch to BUFFER.
| Program used comes from variable `explicit-shell-file-name',
|  or (if that is nil) from the ESHELL environment variable,
|  or else from SHELL if there is no ESHELL.
| If a file `~/.emacs_SHELLNAME' exists, it is given as initial input
|  (Note that this may lose due to a timing error if the shell
|   discards input when it starts up.)
| The buffer is put in Shell mode, giving commands for sending input
| and controlling the subjobs of the shell.  See `shell-mode'.
| See also the variable `shell-prompt-pattern'.
|
| To specify a coding system for converting non-ASCII characters
| in the input and output to the shell, use C-x RET c
| before M-x shell.  You can also specify this with C-x RET p
| in the shell buffer, after you start the shell.
| The default comes from `process-coding-system-alist' and
| `default-process-coding-system'.
|
| The shell file name (sans directories) is used to make a symbol name
| such as `explicit-csh-args'.  If that symbol is a variable,
| its value is used as a list of arguments when invoking the shell.
| Otherwise, one argument `-i' is passed to the shell.
|
| (Type C-h m in the shell buffer for a list of commands.)

FYI i added this to help me create several buffers with predictable names to
help when coding.

This might be helpful if you always want the same shells open for each emacs
session

;; pre-create shell buffers
(defun thias-shell ()
  (interactive)
  (shell)
  (rename-buffer "*Sdefault*")
  (shell)
  (rename-buffer "*Shelper*")
  (shell)
  (rename-buffer "*Scompile*")
  (shell)
  (rename-buffer "*Srun*")
  (split-window-vertically)
  (shell)
  (rename-buffer "*Slog*")
)

I think you meant:

;; pre-create shell buffers
(defun thias-shells ()
   (interactive)
   (shell "*Sdefault*")
   (shell "*Shelper*")
   (shell "*Scompile*")
   (shell "*Srun*")
   (split-window-vertically)
   (shell "*Slog*")
)

[mlathe]

nope i didn't...
but then again i didn't know that that you can pass in an alternate buffer
name.
i guess i should have RTFM.
thanks for the pointer. (still learning!)

Or you could have read my previous reply.  :-)

You're welcome -- even us veterans are still learning!
