List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: emacs-orgmode-bounces+geo-emacs-orgmode=m.gmane.org@gnu.org Sender: "Emacs-orgmode" To: emacs-orgmode@gnu.org Hello, I want to execute shell blocks like follows: #+BEGIN_SRC shell :session n42 :dir /127.0.0.1: :shebang "#!/bin/bash" echo los echo $SHELL echo $BASH echo ready #+end_src The trouble is that the shebang property doesn't work in this case. The script is executed with the login shell of the user and fails because of syntax errors (for instance, if bashisms are used in the script). With my minimal and dangerous knowledge about Org's source code ;), I think the following might work (from ob-shell.el): (defun org-babel-sh-initiate-session (&optional session _params) "Initiate a session named SESSION according to PARAMS." (when (and session (not (string= session "none"))) (save-window-excursion (or (org-babel-comint-buffer-livep session) (progn (let ((explicit-shell-file-name (xxx))) (shell session)) ;; Needed for Emacs 23 since the marker is initially ;; undefined and the filter functions try to use it without ;; checking. (set-marker comint-last-output-start (point)) (get-buffer (current-buffer))))))) Note the let form. Further tasks that have to be done is to add the shebang key to _params, which I hope is available at all places where o-b-s-i-s is evaluated. Further at (xxx) a regexp etc. is needed to transform the shebang line to a shell path suitable for e-s-f-n. Any opinions, please? Depending on the opinions I will implement the approach this week and see if it works as expected. Regards hmw
