To clarify: in the above, find-file-noselect returns a buffer, so
`get-buffer' just returns its argument.  And save-excursion + set-buffer
is better replaced by with-current-buffer.  All in all:

   (with-current-buffer (find-file-noselect "/home/drain/foo.org")
     (insert "test operation"))

find-file-noselect re-uses an existing buffer (if there is one).  So if
you want the equivalent for a shell-style buffer, you could try

  (with-current-buffer
      (or (get-buffer "*shell*")
          (make-comint-in-buffer "shell" nil "/bin/bash"))
    (unless (derived-mode-p 'comint-mode) (shell-mode))
    (insert "test operation"))
