I want to start a shell buffer and then run a command via an Emacs
Lisp function. If I do this:

(shell)
(insert "ls\n")


Emacs will start a shell buffer and insert the command at the prompt
but it seems to be missing the effect of hitting the enter key. Is
there a way to simulate hitting the [enter] key in Emacs Lisp?

Well I found something:

(comint-send-input)

seems to do the trick and simulate manually hitting [enter] in the
shell buffer.

You don't need the extra "\n" at the end of the command, but you may
find the function `comint-send-input' useful.

    (shell)
    (insert "ls")
    (comint-send-input)

If you don't really need the command to support interactive input, you
can also call `shell-command' with the full command string:

    (shell-command "ls")

With an optional second argument, you can send the output to a specific
buffer, i.e.:

    (with-temp-buffer
      (shell-command "ls" (current-buffer))

      ;; More stuff that processes parts of (current-buffer).
      ...)

Thanks Giorgos. shell-command is probably what I should be using in
most cases instead of shell. Didn't know about with-temp-buffer
either.
