How do you control the output window of an Emacs Lisp shell command?

Question

Given something like this:

(global-set-key (kbd "<f4>") (lambda () (interactive) (shell-command "gcc --version")))

Is there a way to get the output to always go into a "new or existing window on the right" versus sometimes doing that, and sometimes putting the output in a little window below the status and command areas (two different possibilities shown below)?

Answer 1

The following works reliable also for one line of output (e.g. "echo hello" instead of "gcc --version"):

(global-set-key (kbd "<f4>")
                (lambda () (interactive)
                   (with-current-buffer (get-buffer-create "*Shell Command Output*")
                     (erase-buffer)
                     (insert (shell-command-to-string "gcc --version"))
                     (display-buffer (current-buffer)))))
