You probably want:

,----
|    (with-current-buffer "*shell*"
|        (goto-char (point-max))
|        (insert "echo hello world"))
`----

Or

,----
|    (switch-to-buffer "*shell*"
|      (goto-char (point-max))
|      (insert "echo hello world"))
`----

All that assume shell is started.
If not just run the shell you want from your function before inserting.


If you want a complete mode to send commands to a shell (even an xterm)
from emacs, have a look at eev-mode.

If you use eshell as shell, the command is `eshell-send-input', but i
think it's better to use enter to be sure you really want to send the
command inserted.

But maybe what you only need is instead of all that is:

(shell-command "echo hello world")

Put point at end of this expression and hit C-x C-e.
