This patch try to support following way: #+begin_src sh :results link :file "/tmp/test.txt" echo "hello" > /tmp/test.txt echo "test" #+end_src
#+RESULTS:
[[file:/tmp/test.txt]]
Because:
- ~org-babel-execute-src-block~
- ~(org-babel-get-src-block-info)~
- (let* ((info .. (apply #'org-babel-merge-params ...))))
- ~org-babel-merge-params~
- [ ] *because* code ~(`(,(or :file :file-ext) . ,value) ...)~
lines logic in function ~org-babel-get-src-block-info~, it
merge "file" ~:results~, so override params plist :results
value ~link~.
- [ ] So I put ~link~ and ~graphics~ "~:results~" type into a
separate group in constant
~org-babel-common-header-args-w-values~.
If anybody has better way, please improve my code.

Subject: [PATCH 1/2] ob-core.el: add :results link type result for babel.
* lisp/ob-core.el (org-babel-execute-src-block): handle :results link
type. Like :results graphics, don't write result to :file specified file.
* etc/ORG-NEWS: declare new :results type "link".
* doc/org-manual.org: add document for new type result "link".
* testing/lisp/test-ob.el (test-ob/result-file-link-type-header-argument):
Add test for new added :results type "link".
